This page lists all new features and fixed issues for each QPR ProcessAnalyzer release.


== Future Release: QPR ProcessAnalyzer 2020.6 (planned release date 2020-08-18) ==  
== Next Release: QPR ProcessAnalyzer 2024.8 (planned release date 2024-12-10) ==
Build number: 2020.6.0.xxxxx, Model compatibility version: x, Database version: xx, PACM file version: x, Protocol version: xx.


'''Notes:'''
See [[Next_Release_Content|the next release content]].
* The legacy process mining models are not supported anymore, and they need to be migrated manually to new models before updating to QPR ProcessAnalyzer 2020.6. The new models use datatables to store events and cases. You can check the model type as follows: Open QPR ProcessAnalyzer Web UI, open the models dropdown list in the header, find a model, open ''Properties'' for the model, and go to the ''Datasources'' tab. If the ''Load from Database'' is ''yes'', the model is a legacy model and requires a migration. The migration can be done by exporting the model as a .pacm file (in the ''Actions'' tab from model properties), and importing the file back using the ''Import Data'' functionality. It's also recommended to delete the legacy models. The eventlog data for the legacy models is not yet removed in QPR ProcessAnalyzer 2020.6 and thus it's possible to rollback to QPR ProcessAnalyzer 2020.5 if needed. The eventlog data for the legacy models will be removed in a future release to save space in the database.


'''Features:'''
== Latest Release: QPR ProcessAnalyzer 2024.7 (build 8234) (released 2024-10-29) ==


'''Fixed issues:'''
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
If using local datatables (stored in SQL Server), the [[PA_Configuration_database_table#SqlServerConnectionString|SqlServerConnectionString]] setting is now mandatory. Starting from QPR ProcessAnalyzer 2024.7, local datatables cannot be created if the setting is not configured. It's recommended to have a separate database for the datatables data, but it's also possible to configure the same connection to the SqlServerConnectionString setting as for the configuration database (in [[Installing_QPR_ProcessAnalyzer_Server#Server_settings_file_(appsettings.json)|appsettings.json]]). See [[QPR_ProcessAnalyzer_System_Architecture|System Architecture]] for more information about the data storage.

== Next Release: QPR ProcessAnalyzer 2020.5 (planned release date 2020-06-26) ==
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Build number: 2020.5.0.xxxxx, Model compatibility version: x, Database version: xx, PACM file version: x, Protocol version: xx.
Check whether there are custom roles in the database (table PA_ROLE) which have the ROL_FLAGS field set to NULL. The NULL values don't work with this release, so set a correct value (either 1, 2, or 3). Following query can be run in the database showing roles which have an incorrect ROL_FLAGS field:
<pre>
SELECT *
FROM [PA_ROLE]
WHERE [ROL_FLAGS] = NULL;
</pre>
</div>

* Dashboards structure is simplified, as panels are removed and presentation objects are placed directly to the dashboard canvas. In addition, panel headers are not available anymore. Presentation objects have now background color, border color, border width and border corner radius, that were previously in the panel level. All existing dashboards are automatically migrated to the newer structure. Existing dashboards that have several presentation objects within a same panel, are positioned on top of the others, so in those cases presentation objects need to be repositioned manually after updating to QPR ProcessAnalyzer 2020.5.
Snowflake user-defined functions (UDF) used by QPR ProcessAnalyzer have been updated to use Python 3.11. Old versions of the functions use Python 3.8 which has been deprecated by Snowflake. Although the old versions are not anymore used by QPR ProcessAnalyzer, they are not automatically deleted and thus Snowflake may send notifications emails about existing deprecated functions. It's recommended to remove the old functions which are following:
* IP address verification of user sessions has been removed. Previously, each user session was only allowed from the same IP address. This kind of security feature won't work with IPv6 addresses which usually change more often than IPv4 addresses.
* QPRPA_UDF_BC_DURATION_BETWEEN_DATES
* QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V2
* QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V3
* QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V4
* QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V5
* QPRPA_UDTF_CLUSTER
* QPRPA_UDTF_CLUSTER_V2
* QPRPA_UDTF_CLUSTER_V3
* QPRPA_UDF_BPMN_IS_CONFORMANT
* QPRPA_UDF_BPMN_CONFORMANCE_VIOLATIONS_FLOWS

== QPR ProcessAnalyzer 2020.4 (release date 2020-05-26) ==
<span id="84516a70"></span>
Build number: 2020.4.0.41643, Model compatibility version: 3, Database version: 71, PACM file version: 7, Protocol version: 33.


'''Notes:'''
== QPR ProcessAnalyzer 2024.6 (build 7414) (released 2024-09-18) ==
* In QPR ProcessAnalyzer 2020.4, the deployment package dashboards come with the installation, so there is no deployment package anymore to be installed. The previous deployment package located in the ''QPR ProcessAnalyzer UI'' project can be deleted when 2020.4 is installed.
* To fix issue ''Datetimes are incorrect in files exported from data grids'' (219377), [[Data Grid Export Service|data grid export service]] needs to be updated from version V001 to V002.
* Issue workaround: After updating to QPR ProcessAnalyzer 2020.4, dashboards containing the root causes analysis give an error message about invalid chart configuration. The problem can be fixed as follows: from the JSON text that appears in the full screen text editor, make the following text replacements: "Case Attribute" --> "Case attribute" and "Attribute Value" --> "Attribute value". When the dashboard is saved, the error doesn't appear anymore.
* To improve performance, for custom expressions in charts it's recommended to replace ''??_remove'' with the [[Generic_Functions_in_QPR_ProcessAnalyzer#RemoveNulls|RemoveNulls]] function. Example: Expression ''Average((_.Attribute("Cost") ??_remove)._)'' can be changed to ''Average(RemoveNulls(_.Attribute("Cost")))''.
* To improve performance, for custom expressions in charts it's recommended to change expressions that make duration aggregations to work in a way that the aggregation is made before converting TimeSpans to integers (e.g. to days). Example: expression ''Average(_.Duration.TotalDays)'' can be changed to ''Average(_.Duration).TotalDays''.
* Issue: In Firefox, when opening a dashboard, an error message "Error in chart settings" might appear (the dashboard is still opened correctly). If the issue appears, it's recommended to use Chrome, where the issue does not appear that often. There are no other workarounds available for the issue.
* Issue: FlowOccurrences and FlowOccurrencesByType properties don't work for Case objects when there are also filter rules applied. Some measures and dimensions use those properties. QPR ProcessAnalyzer 2020.5 will fix the issue, and for earlier versions there is no workaround.


'''Features:'''
'''Features:'''
* 307859: Deployment package dashboards are embedded to QPR ProcessAnalyzer release.
* B-08366: Frontend for [[Object-centric_Process_Mining_Model|OCPM model]] configuration and Snowflake charts using perspectives.
* 307899: RemoveNulls function to remove null values from arrays.

== Additional release for QPR ProcessAnalyzer 2020.3 (release date 2020-04-23) ==  
== Additional release for QPR ProcessAnalyzer 2024.5 (build 6814) (released 2024-07-01) ==
Build number: 2020.3.0.41450, Model compatibility version: 3, Database version: 71, PACM file version: 7, Protocol version: 33.
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Known issue: It's not possible to move projects that existed before updating to this release. The issue will be fixed in the next release. There is a following workaround available: Administrator user can go to the [[Navigation_Menu#Expression_Designer|Expression Designer]] and run the following expression: '''Projects.Modify(#{})'''.
</div>


'''Features''':
'''Fixed issues:'''
* 307902 ChartView improvements for 2020.3 hotfix: Custom expressions have by default datatype "auto", added support for binding to multi-select lists in Variable bindings, bugfix: Custom sorting didn't work in presets, bugfix: Aggregation method for Pivot table was not selected correctly.
* D-14191: Running script by id failed on data import when parameters contained ScriptId.
* D-14183: Fixed issue where flowchart SVG export only exported the visible part of flowchart.


'''Fixed bugs:'''
== Additional release for QPR ProcessAnalyzer 2024.5 (build 6769) (released 2024-06-27)==
* 219370: Dashboards could not be edited by other than administrators.
* 219361: Flowchart sometimes crashed to ThrowKeyNotFoundException when pressing Root Causes button.


== QPR ProcessAnalyzer 2020.3 (release date 2020-04-16) ==
'''Features:'''
Build number: 2020.3.0.41413, Model compatibility version: 3, Database version: 71, PACM file version: 7, Protocol version: 33.


'''Notes:'''
*B-08388: Added backend support for OCPM model perspectives to convert object-centric eventlogs into case-centric.
* Legacy Chart and Gauge presentation objects are removed from QPR ProcessAnalyzer (they are different than ChartView). If there are dashboards containing those types of presentation objects after updating to 2020.3, there will be a placeholder frame instead with an error message of a non-existing presentation object. To change the dashboard, remove those placeholders and replace with ChartViews. It's recommended to make the replacement to ChartViews before the update, because chart and gauge settings cannot be accessed anymore in 2020.3.
* ChartView will change from an HTML presentation object to a native presentation object, which ensures that dashboards will work in future releases when the ChartView is evolving. ChartViews created with 2020.2 will be automatically migrated to the native ChartViews in 2020.3. ChartViews created with 2020.1 or earlier releases need to be updated manually by removing the ChartView from the dashboard and replacing it with a new ChartView.


'''Features:'''
'''Fixed issues:'''
* 307849: Securely stored strings for passwords.
* 307746: ChartView is now a native presentation object instead of an HTML presentation object. ChartView's made in 2020.2 are automatically converted to the native presentation objects.
* 307880: When a datatable model is moved to another project, the linked datatables should also be moved to the project.
* 307556: Functions to expression language to improve usability and performance: CaseCount, EventCount, EventCountByType and Round.
* 307895: SQL scripting command for database commit.
* 307850: Expression language performance improvement by a new way to calling functions and properties.
* 307858: Expression language: Support for array operators.
* 307845: Header buttons layout has been improved.
* 307870: Preprocessings are determined automatically.
* 307761: Functionality that user doesn't have access is now disabled in the dashboard designer and workspace to avoid access denied errors.
* 307839: Generic chart and gauge presentation objects are removed.
* 307863: Automatic redirection to SAML authentication.
* 307872: API support for querying if SAML is configured.
* 307846: Error message further improvements.
* 307888: Error message text changes for Dashboard not found and Multiple dashboards found.
* 307874 & 307887: ChartView and main header has been improved.
 
'''Fixed bugs:'''
* 219341: Analysis function unnecessarily required FilterId parameter.
* 219343: Root causes analysis gave access denied when using Analysis function.
* 219348: Query cancellation caused database connection leakage.
* 219332: "Thread was being aborted" returned to client while loading model from datatable.
* 219321: Removed unnecessary error log lines "Missing expected HttpRequest X-Forwarded-For" that appeared even if UseXForwardedForAsClientIp=false.
* 219335: [_remove ]._ or empty array is not handled correctly in a KPI dimension.
* 219340: default.aspx does not work.
* 219330: EditDashboards permission should be needed for target project when moving dashboards between projects.
* 219347: Queries done by the main header were cancelled when view is changed.
* 219355: Expression language: Was unable to use properties of the parent context in dictionary initialization.
* 219346: PAPO flowchart should have by default median duration shown on flows and flow counts hidden.
* 219333: PAPO generated incorrect filter JSON and unnecessary query.
* 219311: When opened a view by identifier, the view was fetched twice from the server.
* 219329: Unnecessary information was stored in database for dashboard definitions.
* 219362: Issues with session expiration checks.
* 219364: Session expiration with SAML authentication configured gives incorrect error message.
* 219344: Case count view in model manager header and Home view can cause unwanted model loading.
* 219242: Flowchart is not updated correctly after event type filtering.


== QPR ProcessAnalyzer 2020.2 (release date 2020-03-09) ==
*D-14187: Creating local datatables was not possible in Workspace if datatables were stored to the configuration database (i.e., SqlServerConnectionString setting is not used).
Build number: 2020.2.0.41129, Model compatibility version: 3, Database version: 67, PACM file version: 7, Protocol version: 33.


'''Notes:'''
==QPR ProcessAnalyzer 2024.5 (build 6746) (released 2024-06-25)==
* Expression language has now a [[QPR_ProcessAnalyzer_Expressions#Conditional_operator_.28if.29|conditional operator "if"]] and [[QPR_ProcessAnalyzer_Expressions#Define_variables_.28let.29_and_assign_variable_values_.28.3D.29|variable declaration operator "let"]]. In earlier QPR ProcessAnalyzer versions, the expression language had functions [[Generic_Properties_and_Functions_in_QPR_ProcessAnalyzer_Expressions#If|If]] and [[Generic_Properties_and_Functions_in_QPR_ProcessAnalyzer_Expressions#Let|Let]] which earlier could also be written in lowercase (i.e. "if" and "let"). Starting from QPR ProcessAnalyzer 2020.2, the lowercase versions refer to the conditional and variable declaration operators, and the uppercase versions refer to the corresponding functions. If there are expressions containing "If" and "Let" functions written in lowercase, please change them starting with uppercase.
* Issue workaround: The Root Causes analysis don't work (shows empty) in the right side chart (PAPO) of the ''Process Discovery'' view. The issue can be fixed as follows by an administrator: click the ''Edit'' toggle button, click the right side chart, click the ''Edit'' icon in the top right of the chart, click the chart again, click ''Properties'' icon in the top right of the chart, open ''Variables'' tab, find the ''InfluenceAttributeTypeId'' variable, and change its value to empty (instead of ''20''). Click ''Close'' twice to go back to the main level and click ''Save'' button. The issue will be fixed to 2020.3.
* Issue workaround: In ChartView, the ''Duration between events'' measure and dimension don't work when there are filters in use (the chart is empty). Workaround is to add the following ''Suffix expression'' to the measure or dimension settings (without quotes): "''//eventtypes''". The issue will be fixed to 2020.3.

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
* 219040: Clustering analysis expression doesn't take into account model without any case attributes.
Limitation for the maximum amount of data (B-07636) causes a behavior change in in-memory charts that have the Maximum rows settings empty and have the sorting defined. In certain cases, the order in which measures are evaluated changes (due to an internal performance optimization). If there are custom expressions that define variables, the variables may not be available in other measures anymore. As a resolution, either redefine the variables in those measure expressions or add those measures secondarily to the sorting.
* 219001: Case Analysis always limited to 1000 rows (other analyses have the same problem).
</div>
* 219042: PAPO: "Influence Analysis for Case Attributes", value is rounded to closest integer.

* 219062: GetModels is slow for admin.
Default query timeout of 30 minutes has been added for --#ImportOdbcQuery, --#ImportSqlQuery and --#ImportOleDbQuery commands. If a query run is taking longer than the timeout, the query is stopped. The timeout can be adjusted using the '''QueryExecutionTimeout''' parameter. Previously, there has been no timeout, so queries that take more than 30 minutes require configuring a longer timeout.
* 218978: Odd 1 million filter is adapted once you remove your custom filter.
</div>
* 219015: Script Launcher million rows limit when exporting to excel csv.
* 219022: GetModelAsStream webservice not support modelId.

*B-08017: [[Dashboard_in_Expression_Language|Dashboards API]] has been added to expression language, allowing to create, modify and delete dashboards in scripts.
*B-08056: Following properties have been added to [[QPR_ProcessAnalyzer_Objects_in_Expression_Language#User.2FGroup|user objects]] in expression language: IsLocked, LastLockedDate, LastLoginDate.
*B-08053: [[Navigation_Menu#System_Reports|User rights report]] has been refactored to use [[Generic_Properties_in_Expression_Language#RoleAssignments|RoleAssignments]] property in the expression language. The change also simplifies the report as now it only shows the direct role assignments that are visible in the [[Manage_Users_and_Groups|User Management]].
*B-08151: For Snowflake expressions support for following [[SQL_Expressions#Window_functions|windowing functions]]: sum, average, median, min, and max.
*B-08050: When a model is created, the default filter is not created anymore (this is a refactoring that doesn't have any impact on user interface).

Settings can be configured in [[Web.config_file_in_QPR_ProcessAnalyzer#Qpr.ProcessAnalyzer.Common.Properties.Settings_Section | web.config]] or from the [[QPR_ProcessAnalyzer_Model_JSON_Settings#Memory_Usage_Settings | model JSON settings]].
Following legacy analyses have been removed: Operation log (analysis number: 12), Root causes (14), Correlations (15), Idea feed (16) and Duration influence (29). This functionality may be in use in SQL scripts (in [[SQL_Scripting_Commands#--.23GetAnalysis|--#GetAnalysis]] command), and thus needs to be changed to the [[SQL_Scripting_Commands#--.23RunQuery|--#RunQuery]] command (see the [[RunQuery_Script_Examples|examples page]] how each legacy analysis can be replaced). The OperationLog analysis is replaced by the [[Generic_Properties_in_Expression_Language#OperationLog|OperationLog function]] and the Infcluencers analysis is replaced by the [[FindRootCauses_Function|FindRootCauses function]].


'''Fixed bugs in QPR ProcessAnalyzer UI:'''
Following script can be run in the [[Navigation_Menu#Expression_Designer|Expression Designer]] to show whether there are scripts that use the removed analyses (and thus require migration):
* 218838: KPI analysis: Event Occurrence Time isn't calculated properly, e.g. Period=Month fails.
<pre>
let removedAnalyses = [12, 14, 15, 16, 29];
OrderByDescending(Flatten(Projects.Scripts).Where({
  let scr = _;Sum(removedAnalyses.("'AnalysisType','" + _ + "')").{let num=_;(scr.code ?? "").Replace(" ", "").Replace("\t", "").Replace("\n", "").Replace("\r\n", "").Replace("\r", "").Contains(num)})>0;
}),LastRunStart).(Project.Name + ": " + name + " (id: " + id + ") (last run: " + (LastRunStart ?? "N/A") + ")");
</pre>

* 218880: PAPO: odbc case and event attributes are not shown in dropdown menu.
By default, Snowflake ODBC driver generates quite much logging to files which might unnecessarily fill up the disk space. It's recommended to set the LogLevel parameter to value 0. The path where the logs are created can be seen in Windows registry (key LogPath). More information about configuring Snowflake ODBC parameters: https://docs.snowflake.com/en/developer-guide/odbc/odbc-parameters.
* 218877: Support material - Project admins are not able to create new users.
</div>
* 218898: Importing XES file with xmlns -definition fails.
* 218893: Model status shows incorrectly "offline" when Model event log is in memory and Model information not.
* 218917: BaseContext.EvaluateChildExpression with given root object iterates the root object if it is an array.

Latest revision as of 17:20, 30 October 2024

This page lists all new features and fixed issues for each QPR ProcessAnalyzer release.

Next Release: QPR ProcessAnalyzer 2024.8 (planned release date 2024-12-10)

See the next release content.

Latest Release: QPR ProcessAnalyzer 2024.7 (build 8234) (released 2024-10-29)

If using local datatables (stored in SQL Server), the SqlServerConnectionString setting is now mandatory. Starting from QPR ProcessAnalyzer 2024.7, local datatables cannot be created if the setting is not configured. It's recommended to have a separate database for the datatables data, but it's also possible to configure the same connection to the SqlServerConnectionString setting as for the configuration database (in appsettings.json). See System Architecture for more information about the data storage.

Check whether there are custom roles in the database (table PA_ROLE) which have the ROL_FLAGS field set to NULL. The NULL values don't work with this release, so set a correct value (either 1, 2, or 3). Following query can be run in the database showing roles which have an incorrect ROL_FLAGS field:

SELECT *
FROM [PA_ROLE]
WHERE [ROL_FLAGS] = NULL;

Snowflake user-defined functions (UDF) used by QPR ProcessAnalyzer have been updated to use Python 3.11. Old versions of the functions use Python 3.8 which has been deprecated by Snowflake. Although the old versions are not anymore used by QPR ProcessAnalyzer, they are not automatically deleted and thus Snowflake may send notifications emails about existing deprecated functions. It's recommended to remove the old functions which are following:

  • QPRPA_UDF_BC_DURATION_BETWEEN_DATES
  • QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V2
  • QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V3
  • QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V4
  • QPRPA_UDF_BC_DURATION_BETWEEN_DATES_V5
  • QPRPA_UDTF_CLUSTER
  • QPRPA_UDTF_CLUSTER_V2
  • QPRPA_UDTF_CLUSTER_V3
  • QPRPA_UDF_BPMN_IS_CONFORMANT

QPR ProcessAnalyzer 2023.7 (build 4326) (released 2023-11-28)

Limitation for the maximum amount of data (B-07636) causes a behavior change in in-memory charts that have the Maximum rows settings empty and have the sorting defined. In certain cases, the order in which measures are evaluated changes (due to an internal performance optimization). If there are custom expressions that define variables, the variables may not be available in other measures anymore. As a resolution, either redefine the variables in those measure expressions or add those measures secondarily to the sorting.

Default query timeout of 30 minutes has been added for --#ImportOdbcQuery, --#ImportSqlQuery and --#ImportOleDbQuery commands. If a query run is taking longer than the timeout, the query is stopped. The timeout can be adjusted using the QueryExecutionTimeout parameter. Previously, there has been no timeout, so queries that take more than 30 minutes require configuring a longer timeout.

Incorrectly configured linked settings in charts (available in the Advanced tab) give now an error message, if they are referring to non-existing measures, dimensions or columns. Previously, incorrect linked settings were ignored. To fix the error message, remove the incorrect linked settings.

Features:

  • B-07511: Datatables have a dialog to view datatable properties, write description, set the Snowflake source table, add/modify/delete columns, and set the datatable key.

  • B-08091: Duration between events calculation ignores negative durations in Snowflake.
  • B-08091: Chart loading animation has been renewed.
  • B-07636: To prevent dashboards from jamming when querying too much data, added limitations to the amount of data that charts can visualize. Note that the limitation concerns the aggregated data that is visualized, not the source event log data.
  • B-08017: Dashboards API has been added to expression language, allowing to create, modify and delete dashboards in scripts.
  • B-08056: Following properties have been added to user objects in expression language: IsLocked, LastLockedDate, LastLoginDate.
  • B-08053: User rights report has been refactored to use RoleAssignments property in the expression language. The change also simplifies the report as now it only shows the direct role assignments that are visible in the User Management.
  • B-08151: For Snowflake expressions support for following windowing functions: sum, average, median, min, and max.
  • B-08050: When a model is created, the default filter is not created anymore (this is a refactoring that doesn't have any impact on user interface).

  • B-08092: Updated backend components.

Fixed issues:

  • D-13876: In CreateSnowflakeConnection function, ProjectId parameter is optional when OdbcConnectionStringKey is not specified.

QPR ProcessAnalyzer 2023.5 (build 3304) (released 2023-09-05)

In Big Data Chart, the Case conformance measure and dimension has changed in a way that now it provides boolean values (true/false) instead of integer values (1/0). If colorMappings are used for this measure or dimension to set specific colors to visualize conformant and nonconformant cases, the mapped values need to be changed as follows: 1 -> true and 0 -> false. Without the change, the mapped colors are not effective.

Exmaple: Old configuration:

"colorMappings": {
  "1": "#36d475ff",
  "0": "#f5403bff"
}

New configuration:

"colorMappings": {
  "true": "#36d475ff",
  "false": "#f5403bff"
}

Big data chart support of models with local datatables (i.e., SQL Server stored) is deprecated. Big data chart has allowed to process data both in Snowflake and SQL Server. Now the support for SQL Server is deprecated and the Big data chart will only support calculation in Snowflake. If there are big data charts using SQL Server calculation, either migrate data to Snowflake or switch to in-memory charts (requiring to load data in-memory).

Following legacy analyses have been removed: Operation log (analysis number: 12), Root causes (14), Correlations (15), Idea feed (16) and Duration influence (29). This functionality may be in use in SQL scripts (in --#GetAnalysis command), and thus needs to be changed to the --#RunQuery command (see the examples page how each legacy analysis can be replaced). The OperationLog analysis is replaced by the OperationLog function and the Infcluencers analysis is replaced by the FindRootCauses function.

Following script can be run in the Expression Designer to show whether there are scripts that use the removed analyses (and thus require migration):

let removedAnalyses = [12, 14, 15, 16, 29];
OrderByDescending(Flatten(Projects.Scripts).Where({
  let scr = _;Sum(removedAnalyses.("'AnalysisType','" + _ + "')").{let num=_;(scr.code ?? "").Replace(" ", "").Replace("\t", "").Replace("\n", "").Replace("\r\n", "").Replace("\r", "").Contains(num)})>0;
}),LastRunStart).(Project.Name + ": " + name + " (id: " + id + ") (last run: " + (LastRunStart ?? "N/A") + ")");

By default, Snowflake ODBC driver generates quite much logging to files which might unnecessarily fill up the disk space. It's recommended to set the LogLevel parameter to value 0. The path where the logs are created can be seen in Windows registry (key LogPath). More information about configuring Snowflake ODBC parameters: https://docs.snowflake.com/en/developer-guide/odbc/odbc-parameters.
