When installing 2021.9 server, note that there is a change in the web.config file: httpRuntime element includes now targetFramework="4.7.1" attribute.
Known issue: There may be old invalid models which don't work with QPR ProcessAnalyzer 2024.8. The following query can be run in the [[Navigation_Menu#Expression_Designer|Expression Designer]] (with System administrator user) to list such models:
<pre>
Models.Where(!IsOcelModel && Configuration.TryGetValue("DataSource").TryGetValue("Events").TryGetValue("DataSourceType") == _EMPTY).(Project.Name + ": " + Name + " (" + Id + ")")
</pre>
Those models don't have a valid datasource defined and thus they are likely not is use. Easiest solution is to delete those models with following command:
<pre>
ModelById(<id>).DeletePermanently()
</pre>
</div>

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Starting from 2021.9, QPR ProcessAnalyzer ScriptLauncher uses Web API instead of legacy WCF API. To take the Web API into use, ScriptLauncher needs to be updated to 2021.9. In addition, in the ScriptLauncher configuration file, ''ConnectionType'' setting needs to be ''WebApi'' (the setting is in place in the 2021.9 release package). The new Web API based ScriptLauncher is not anymore dependent on the API protocol version, and thus starting from 2021.9, information about the protocol version is not published. The old ScriptLauncher using protocol version 39 still works with the 2021.9, but as the WCF API is deprecated, ScriptLauncher update is mandatory before updating to 2022.1.
SQL Server database compatibility level needs to be at least 130 (corresponding to SQL Server 2016) for databases used by QPR ProcessAnalyzer. When using a supported version of SQL Server, the database compatibility level might still be unsupported, so please check to used compatibility level. It's recommended to set the highest available compatibility level. More information: https://learn.microsoft.com/en-us/sql/relational-databases/databases/view-or-change-the-compatibility-level-of-a-database.

The predefined analyses operations that QPR ProcessAnalyzer has traditionally been based on, are now deprecated and will be replaced by functionality provided by the expression language. In practice, the following features will be removed:
[[External_Content|External content]] component doesn't allow to embed websites from other origins than the QPR ProcessAnalyzer server. This is due to a change in the Content security policy (CSP) HTTP header (more information: [[QPR_ProcessAnalyzer_Security_Hardening#Added_HTTP_Headers|Security hardening]]). The content security policy HTTP header can be modified in the [[Installing_QPR_ProcessAnalyzer_Server#Server_settings_file_(appsettings.json)|appsettings.json file]]. More information about the ''same-origin policy'': https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy.
* [[SQL_Scripting_Commands#--.23GetAnalysis|--#GetAnalysis]] command in SQL scripting: If there are scripts using that command, replace them with the new [[SQL_Scripting_Commands#--.23RunQuery|--#RunQuery]] which uses the expression language to query data.
* [[DataFrame_in_Expression_Language#Extract_Data_to_DataFrames|Analysis]] function in expression language: If using that function, replace it with other functionalities provided by the expression language.
* POST /api/analysis/{analysisType} endpoint in the Web API: If using that endpoint in customized solutions, call the [[Web_API:_Expression/query|/api/expression/query]] endpoint instead.

QPR ProcessAnalyzer WCF API is now deprecated and it will not be available starting from 2022.1 release. All customized integrations and other solutions that use WCF API need to be converted to use [[QPR_ProcessAnalyzer_API|Web API]]. Note that there may also exist scripts that contact the WCF API using the [[SQL_Scripting_Commands#--.23CallWebService|--#CallWebService]] command. The API generation in use can be distinguished from the url: if it contains "/MainService.svc" the connection is to the WCF API and changes are required.
QPR ProcessAnalyzer now uses the Microsoft.Data.SqlClient library for SQL server connection instead of the System.Data.SqlClient library, and there are slight differences with the connection string parameter default values. If using a self-signed certificate in the SQL Server with the encrypted connection, it might require to add '''TrustServerCertificate=True''' to the connection string, so that QPR ProcessAnalyzer will trust the self-signed certificate and allow the database connection.

SQL scripting commands that create datatables and temporary tables, create the tables now using specific column data types (such as NVARCHAR(MAX), INT, FLOAT, DATETIME2, BIT) instead of SQL_VARIANT. This may affect SQL commands that have relied on the SQL_VARIANT column type.
Project ''Designer'' and ''Administrator'' roles can now create models and datatables in the project. Earlier these operations required the global ''Create models'' role. This global role is now renamed to ''Create projects'', describing its new purpose.

== Latest Release: QPR ProcessAnalyzer 2021.8 (build 614) (released 2021-11-02) ==
<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.

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
Known issue in 2021.8: Some dashboards created with earlier releases, may give following error when opened: ''Chart settings are invalid, and the chart may not work correctly. Type of property "measures/0/nullValue" must be string."'' Despite the error message, the dashboard still works correctly. The issue can be resolved by going through all charts in the dashboard and opening the ''Chart settings'' (in the ''Advanced'' tab). If the settings contain one of the following: ''nullValue: null'', ''emptyStringValue: null'', ''trueValue: null'' or ''falseValue: null'', replace them follows: ''nullValue: ""'', ''emptyStringValue: ""'', ''trueValue: ""'', ''falseValue: ""''. When changes have been made, save the dashboard and check that there is no error, when the dashboard is opened. This issue will also be fixed in the next release, and if decided to wait for it, there is no need to edit the dashboards.
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;">
Known issue in 2021.8: Some dashboards created with earlier releases, may give following error when opened: ''Chart settings are invalid, and the chart may not work correctly. Property "expressionType" is required in dimensions/0."'' In addition to the error message, some charts in the dashboard may not work correctly. This issue appears if there are empty measures or dimensions ("none" selected) above defined measures or dimensions. The issue can be resolved by removing the empty measures and dimensions by clicking the ''Remove'' button for the measure/dimension. This may affect how the remaining measures and dimensions are mapped to the visualization, so the mappings may need to be adjusted in the measure/dimension settings. When changes have been made, save the dashboard and check that there is no error, when the dashboard is opened. This issue will also be fixed in the next release, and if decided to wait for it, there is no need to edit the dashboards.
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

There is a change in the expression language behavior, as now existing variables cannot be reinitialized using the '''let''' operator. Thus, an error is given, if there is already a variable with the same name in the same scope. The new behavior reflects better how programming languages usually work, and also it's able to spot likely bugs in expression scripts.
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(#{})'''.

'''Fixed issues:'''  
There is a breaking change in 2021.4 related to using tags in custom expressions: If a tag provides a string value, before it was written e.g. ''Attribute("<#AutomationAttribute>")'', but now it needs to be written ''Attribute(<#AutomationAttribute>)'', because the quotation marks of the string literal now come with the value replacement. The former will cause error in 2021.4, as there will be two sets of quotation marks. This problem does not concern other type of values (e.g. numeric), as they don't have quotation marks.
</div>


<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
*D-14045: Fixed issue where users with Viewer or Analyzer role couldn't create filters in Snowflake models.
Scripts that are stored to the ''model'' or ''user'' context are not available in the scripting web UI (scripts in ''project'' and ''system'' context are available). If you have scripts in the model or user context, they need to be recreated in the project or system context using the Excel Client latest in 2021.4. Starting from 2021.5, scripts in the model or user context are preserved in the system, but cannot be used anymore (and they will be removed in a future release).

==QPR ProcessAnalyzer 2024.2 (build 5438) (released 2024-02-21)==
Tables used in dashboards are updated to the next generation of Syncfusion JS2 components. The [[QPR_ProcessAnalyzer_Chart#Visualization_Settings|Custom layout]] settings (defined as JSON) of the table might not be compatible between the generations, and thus they need to be changed manually after updating to 2021.4. See instructions how to migrate settings between the generations of the component: https://ej2.syncfusion.com/documentation/grid/ej1-api-migration/.

<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 2021.4, the [[Data_Grid_Export_Service|Data Grid Export Service]] (used for exporting tables as Excel files) is not needed anymore. The renewed table is able to create export files in the browser side without using any server/cloud side service. If the Data Grid Export Service has previously been installed, it's recommended to uninstall it for security reasons (to reduce attack surface).
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.

There is a new step in the QPR ProcessAnalyzer server installation instructions for allowing large process mining models: [[Installing_QPR_ProcessAnalyzer_Server#.Net_Configuration:_gcAllowVeryLargeObjects|.Net configuration: gcAllowVeryLargeObjects]]. The change should also be done for earlier QPR ProcessAnalyzer server versions if using models that have more than 50 million events.
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).

There is a potential performance issue with the list of models in the header, which may appear when there are dozens of models in the list. When there are lot of models, the models list jams the UI when opened. The next release (build 163) has solved the issue.

QPR ProcessAnalyzer 2021.1 does not have the '''Data Grid''' and '''HTML''' presentation objects, and they have been replaced by easier-to-use and more powerful [[QPR_ProcessAnalyzer_Chart|Chart]] presentation object, which supports many layouts such as [[QPR_ProcessAnalyzer_Table|tables]]. After updating to QPR ProcessAnalyzer 2021.1, existing dashboards containing Data Grid and HTML presentation objects will contain a placeholder with a message that the presentation object doesn't exist. That placeholder can be removed and replaced with the Chart presentation object. If you need to preserve settings for the removed presentation objects, that needs to be done before updating to QPR ProcessAnalyzer 2021.1.
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.

Data types of the datatables and temporary tables created by the [[SQL Scripting Commands#--.23ImportSapQuery|--#ImportSapQuery]] command has been changed: previously data types were NVARCHAR(255) for all columns. Now the maximum length in the NVARCHAR data type depends on the SAP data field length. This optimizes the space needed for data storage. In addition, there is a new parameter '''ConvertDataTypes''' allowing to specify which data types are converted correctly instead of using textual format.
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.

Release: QPR ProcessAnalyzer 2024.8 (build 8937) (released 2024-12-11)

Known issue: There may be old invalid models which don't work with QPR ProcessAnalyzer 2024.8. The following query can be run in the Expression Designer (with System administrator user) to list such models: 

Models.Where(!IsOcelModel && Configuration.TryGetValue("DataSource").TryGetValue("Events").TryGetValue("DataSourceType") == _EMPTY).(Project.Name + ": " + Name + " (" + Id + ")")

Those models don't have a valid datasource defined and thus they are likely not is use. Easiest solution is to delete those models with following command: 

ModelById(<id>).DeletePermanently()

SQL Server database compatibility level needs to be at least 130 (corresponding to SQL Server 2016) for databases used by QPR ProcessAnalyzer. When using a supported version of SQL Server, the database compatibility level might still be unsupported, so please check to used compatibility level. It's recommended to set the highest available compatibility level. More information: https://learn.microsoft.com/en-us/sql/relational-databases/databases/view-or-change-the-compatibility-level-of-a-database.

External content component doesn't allow to embed websites from other origins than the QPR ProcessAnalyzer server. This is due to a change in the Content security policy (CSP) HTTP header (more information: Security hardening). The content security policy HTTP header can be modified in the appsettings.json file. More information about the same-origin policy: https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy.

QPR ProcessAnalyzer now uses the Microsoft.Data.SqlClient library for SQL server connection instead of the System.Data.SqlClient library, and there are slight differences with the connection string parameter default values. If using a self-signed certificate in the SQL Server with the encrypted connection, it might require to add TrustServerCertificate=True to the connection string, so that QPR ProcessAnalyzer will trust the self-signed certificate and allow the database connection.

Project Designer and Administrator roles can now create models and datatables in the project. Earlier these operations required the global Create models role. This global role is now renamed to Create projects, describing its new purpose.

Features

  • B-08395: Added native object-centric flowchart showing predefined measures.
  • B-08396: Object attributes are now available as case attributes in object-centric perspective.
  • B-08449: Snowflake Native App supports project-specific database, schema, and warehouse.
  • B-08432: Decision intelligence event log prediction and simulation has been integrated into QPR ProcessAnalyzer.
  • B-03062: Project Designer and Administrator roles can now create models and datatables, and global "Create models" role changed to "Create projects".
  • B-08471: Model properties dialog has been simplified for Native App to exclude in-memory model datasources.
  • B-08504: Charts don't automatically change case/event attributes and event types when encountering non-existing selections.
  • B-08522: Optimized Snowflake queries that do not need event data.
  • B-08454: Optimized SQL executed in Snowflake by removing unnecessary column type casts.
  • B-08507: Migrated tables for scripts and script logs to Entity Framework.
  • B-08519: Migrated user management tables to Entity Framework.
  • B-08539: Migrated model, project and filter tables to Entity Framework.
  • B-08514: Updated translations for release 2024.8.
  • B-08515: Frontend components have been updated.
  • B-08513: Backend components have been updated.

Fixed issues

  • D-14320: On-screen setting didn't work when "dynamicType" is "DataTablesOfProject".

  • D-14286: Fixed issue in model import which sometimes created partially configured model.
  • D-14315: Filtering for custom dimensions didn't work, if expression refers to measures with variables.

  • D-14245: When dialog was opened in Workspace, console showed following error: "Blocked aria-hidden on a <button> element because the element that just received focus ...".

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
