<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.
'''Fixed issues:'''
</div>
* D-13826: Measures or dimensions with case or event attribute and value selections incorrectly removed calculated attributes when dashboard was opened or chart settings were changed.
* D-13821: Font size of some Highcharts tooltips was too small. Issue appeared when there were tooltips mappings in measures or dimensions.
* D-13810: Simplified help links: now all Help buttons go to the QPR ProcessAnalyzer wiki main page.
* D-13822: Snowflake clustering analysis showed empty strings and nulls as case attribute values in an unclear way as just nothing.

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
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 [[Measure,_Dimension_and_Column_Settings#Other_settings|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.
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>

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
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 switch to in-memory charts (requiring to load data in-memory) or migrate data to Snowflake.
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
* QPRPA_UDF_BPMN_CONFORMANCE_VIOLATIONS_FLOWS

'''Features'''
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]].

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.
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(#{})'''.

This release contains a potentially severe issue, where some dashboards completely jam the system by generating lot of calculations. The issue may appear in dashboards that have been created in earlier releases and containing the Root causes preset with default settings. The issue will be fixed by the next release. The issue can be worked around by exporting the affected dashboard, modifying the dashboard file manually and importing the dashboard back. The required modification is to remove line(s) containing <pre>"preset": "RootCauses"</pre> and the comma from the preceding line.
The legacy User permissions report (analysis number 11) and Filters report (analysis number 30) used in SQL scripts have been removed. Use instead the expressions language to query filters and user permissions, e.g., [[QPR_ProcessAnalyzer_Objects_in_Expression_Language#Filter|Models.Filters]] and [[Generic_Properties_in_Expression_Language#RoleAssignments|RoleAssignments]] property.

Following legacy analyses have been removed: Cases (analysis number: 5), Events (6), and EventTypes (7). 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). Note that the legacy analyses removal don't affect the dashboarding functionality.
New version of the Design diagram component has been improved with object-specific measures, and the previous common measures are not migrated into object-specific measures. Thus, the measures need to be configured again, or manually edit the chart json settings (if needed please ask instructions from QPR CustomerCare).

==QPR ProcessAnalyzer 2024.1 (build 4784) (released 2024-01-10)==


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):

QPR ProcessAnalyzer Server and QPR ScriptLauncher are now using .Net 8 (previous was .Net 6). When updating to this release, install the .Net 8 Runtime ([[Updating_QPR_ProcessAnalyzer_Server|see more]]). The .Net 6 doesn't need to be uninstalled immediately because .Net 6 and .Net 8 work side-by-side, but due to security reasons, the unused .Net 6 should eventually be uninstalled.
let removedAnalyses = [5, 6, 7];
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;

Starting from QPR ProcessAnalyzer 2023.1, the '''.NET Desktop Runtime''' is not needed anymore for QPR ProcessAnalyzer Server, so it can be uninstalled. Also for QPR ScriptLauncher, ''.NET Desktop Runtime'' is not needed, but instead install the '''.NET Runtime''' (which is more lightweight). ''.NET Desktop Runtime'' contains the ''.NET Runtime'', so the actions are not mandatory when updating to QPR ProcessAnalyzer 2023.1.
In this release, all filters that don't contain any filter rules, are removed. These are legacy filters which have not been visible in the UI.

== Additional release for QPR ProcessAnalyzer 2022.8 (build 1397) (released 2023-01-11) ==
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
This release fixes an issue where extracting large datasets from SAP increases memory consumption considerably and may lead to out-of-memory error. This release contains packages for both QPR ScriptLauncher and QPR ProcessAnalyzer Server. If SAP extractions are done using QPR ScriptLauncher in client side mode (ExecuteInClientSide=1), it's enough to update QPR ScriptLauncher to fix this issue.
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.
</div>
</div>


'''Fixed issues:'''
* D-12941: Extracting data from SAP consumed unnecessary lot of memory and may have led to out-of-memory error (both when running using QPR ScriptLauncher and in server side).
== QPR ProcessAnalyzer 2022.8 (build 1396) (released 2022-12-30) ==
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Creating datatables with duplicate names in the same project is prevented, and possible existing duplicate names are automatically changed to unique names with a random suffix. If there are duplicate names, they can be renamed either before updating QPR ProcessAnalyzer (to avoid automatic renaming) or after the update (by changing suffixed names). If the renamed datatables are used by models, the linkage will break because it's based on the datatable name. Creating duplicate datatables has already been prevented in the UI, but the improved method works also in the API level.
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.
 
Following SQL query can be used to list datatables (and project id) having duplicate names:
SELECT ITA_NAME, ITA_PROJECT_ID
FROM PA_INTEGRATION_TABLE
GROUP BY ITA_NAME, ITA_PROJECT_ID
HAVING Count(*) > 1
</div>
</div>


<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
If trying to use business calendar for a model that doesn't have the business calendar defined, there will now be an error message instead of showing the chart. Either unselect the business calendar checkbox for the measure or dimension, or define a business calendar to the model. In this situation in earlier releases the business calendar was ignored and full time calculation used.
Incorrectly configured [[Chart_Linked_Settings|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.

== QPR ProcessAnalyzer 2022.7 (build 1331) (released 2022-11-15) ==
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Starting from QPR ProcessAnalyzer 2022.7, to improve security expression language operations that modify data or connect to external datasources are prevented in dashboard custom expressions. The limitation is required, because when a dashboard is opened, its expressions are run with the user's permissions, and the user need to trust the expressions don't perform any unexpected operations, such as delete data. The full functionality of the expression language is available in the scripts and in the Expression Designer.
 
The following functions and operations are prevented in dashboards: SendEmail(), CallWebService(), ImportOdbc(), ImportOdbcSecure(), Model.DeletePermanently(), Model.Restore(), Model.TriggerNotifications(), Project.DeletePermanently(), Project.Restore(), Project.CreateDatatable(), Datatable.AddColumn(), Datatable.DeletePermanently(), Datatable.Import(), Datatable.Merge(), Datatable.RemoveColumns(), Datatable.RenameColumns(), Datatable.Truncate(), RecycleBin.DeletePermanently(), and call SQL script. Calling expression scripts is allowed, but in the script all previously mentioned operations are prevented.


Following SQL query can be executed in the QPR ProcessAnalyzer metadata database to reveal dashboards that potentially have prevented expressions:

This release contains fixes to following major issues:
Big data chart support of models with local datatables (i.e., SQL Server stored) is removed in this release. 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).
* Older QPR ScriptLauncher versions (<=2022.5) don't work with this release, when using the client side import. As a workaround, if updating to QPR ProcessAnalyzer 2022.6, also update QPR ScriptLauncher. Hotfix will be released to recover the backwards compatibility.
* When pressing the Add measure/Add dimension button in the chart settings, the chart settings dialog stop working. The workaround is to add the new measure/dimension to the bottom and use the Move up button to get the desired order of measures/dimensions. This issue will also be fixed in the hotfix.
* ETL scripts run using QPR ScriptLauncher in the client side import mode don't work if there is an import operation taking more than 10 minutes. This is because during the import, QPR ScriptLauncher erroneusly doesn't send the heartbeats to QPR ProcessAnalyzer Server, which then stops the script, believing QPR ScriptLauncher has stopped working. This issue occurs in all QPR ScriptLauncher versions. This issue will be fixed to QPR ProcessAnalyzer Server in the hotfix (i.e., no need to update ScriptLauncher).

== QPR ProcessAnalyzer 2023.5 (build 3304) (released 2023-09-05)==
QPR ProcessAnalyzer Server and QPR ScriptLauncher use now .NET 6 (instead of legacy .NET Framework). The hardware requirements are same, but the .NET 6 Runtime needs to be installed to machines running QPR ProcessAnalyzer Server and QPR ScriptLauncher. See more on the [[Updating_QPR_ProcessAnalyzer_Server|updating QPR ProcessAnalyzer]] instructions. Note that the IIS deployment script is not available anymore. QPR ScriptLauncher update is not mandatory (i.e., .Net Framework based QPR ScriptLauncher works with the .Net 6 based QPR ProcessAnalyzer Server), but update is recommended due to bug fixes made to the QPR ScriptLauncher.

Following legacy analyses have been removed: Flowchart (analysis number: 0), Variations (8), Duration (9), Profiling (10), and Flows (13). This functionality may have been used in the SQL scripts. Note that this change doesn't affect the functionality available in the QPR ProcessAnalyzer web UI.
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 [[Measure,_Dimension_and_Column_Settings#Other_settings|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.


Following script can be run in the [[Navigation_Menu#Expression_Designer|Expression Designer]] to show whether there are scripts in the system that likely use the removed analyses:
Exmaple: Old configuration:

Datatables can be stored to a separate SQL Server database, i.e., the datatables are not anymore created to the QPR ProcessAnalyzer metadata database. This improves performance as data intensive operations are isolated from metadata operations. To take the feature into use, create a new database in SQL Server and set the [[PA_Configuration_database_table#General_Settings|SqlServerConnectionString]] setting in the configuration table to connect to that database. When the configuration has been made, all new datatables are created to the datatables database. Pre-existing datatables are still located in the metadata database. To get the pre-existing datatables to the new database, they need to be recreated, which can be done by creating a duplicate of the datatable. Support for the metadata database stored datatables is continued, but deprecating the support in future will be considered.
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: Variations Chart (analysis number: 1), Event Types Chart (4), Models (17), Model Report (21), Project Report (22), Datatable Report (23), and Script Report (24). To replace these analyses, use the corresponding native functionality in the expression language.
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]].

Security hardening instructions to set the [[QPR_ProcessAnalyzer_Security_Hardening#Add_Security_Related_HTTP_Headers_in_IIS|Content-Security-Policy]] http header, has changed. In addition, the '''img-src''' directive includes also '''blob:''' urls (this allows to export Highcharts charts).
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.

Latest revision as of 12:25, 19 November 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
  • QPRPA_UDF_BPMN_CONFORMANCE_VIOLATIONS_FLOWS

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-08150: Added setting Apply chart filters first to determine whether chart filter rules or dashboard filter rules are applied first when chart queries are filtered.
  • B-08091: When filtering charts in Snowflake, case attribute filter is created instead of case id filter.
  • B-08091: New setting to define whether cases or events are filtered by default.
  • B-08091: New preset "Looping paths" to detect whether there are repeating patterns of events.
  • 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-08123: Translation updates for 2023.7.
  • 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.
