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 in use, either switch to in-memory charts (requiring to load data in-memory) or migrate data to Snowflake.
Known issue: If the [[PA_Configuration_database_table#:~:text=DefaultUiLanguage|DefaultUiLanguage]] system configuration is not defined, users who haven't changed their own language, are unable to login. To prevent this problem, please ensure the DefaultUiLanguage is defined. The next release will fix this issue (D-14706).

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]].
Content-Security-Policy (CSP) HTTP header has been updated to enhance security by implementing more restrictive settings. The following directives have been added:
* object-src 'none'
* frame-ancestors 'self'
* form-action 'none'
* base-uri 'none'
* worker-src blob:


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):
These new restrictions may affect usage that has previously been possible. For example, with the new settings, QPR ProcessAnalyzer can be embedded to a website only within the same origin. For detailed instructions on embedding QPR ProcessAnalyzer on a different website, please refer to [[Embed_to_Website|this quide]]. Additionally, for information on modifying the CSP settings, see documentation for [[QPR_ProcessAnalyzer_Security_Hardening#HTTP_Response_Headers|security hardening]].

By default the 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.
In the QPR ProcessAnalyzer 2025.6 Native App, the release version number is not displayed correctly in the User Settings dialog. This omission does not have any other complications. QPR ProcessAnalyzer 2025.6 is the only release with this issue, making it possible to identify this release despite the missing version number. This issue is specific to the Native App only. The next release will fix this issue (D-14703).

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
* Navigation menu is now displaying dashboards from open dashboard's project or from selected Workspace project (earlier dashboards were shown from the selected model's project). (B-08673)
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.

===Fixed issues===
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.
* Fixed issue where AI Agent made unnecessary queries when filtering dashboard, and also opening dashboard with lot of chart may have been slow. (D-14503)
* When datatable columns were modified, queries to the data may have given "Invalid identifier" error. (D-14507)
* Clustering analysis didn't work with object-centric models. (D-14486)
* When a new groups is added, it's selected by default in the Manage Users dialog. Also clicking a selected group does not deselect it. (D-14491)
* Deleting last group didn't remove the group from the list. (D-14504)


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):

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.
There is an issue causing some dashboards having more than 50 charts to open slowly. The issue has been fixed in the next release by D-14503.

<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.

* 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) ==

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.
There is a potentially serious issue that can cause the system to stop responding, when opening the Scripts tab in the Workspace. The issue has been fixed in the next release (build 9725) by D-14506.
 
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

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.
Object-centric model simplification in the story B-08667 (object attributes can only have a single value) doesn't work with this release. The issue has been fixed in the next release (build 9725) by B-08683.

== QPR ProcessAnalyzer 2022.7 (build 1331) (released 2022-11-15) ==
===Other improvements===
<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
* Logging has been set to Warning level for Native App to avoid excessive number of log entries to Snowflake events table. (B-08687)
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.
* Datatable duplication is now synchronous in Snowflake until 30 seconds to avoid showing the created duplicate datatable with zero rows while the operation is still in progress. (B-08634)
 
* Improved Snowflake cache table creation logic when there are multiple simultaneous queries. (B-08622)
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.
* Refactored SQL Server operations to improve robustness and avoid leaking database connections. (B-08649)
* Frontend components have been updated. (B-08638)
* Backend components have been updated. (B-08639)
* Translations have been updated. (B-08640)


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

== Additional release for QPR ProcessAnalyzer 2022.6 (build 1262) (released 2022-10-19) ==
New features presentation: [https://files.qpr.com/releases/QPR_ProcessAnalyzer_2025_2.pdf QPR_ProcessAnalyzer_2025_2.pdf]


<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 contains fixes to following major issues:
Detection of models with incomplete datasource configuration has been improved, and now models where the event timestamp column type is string, are not anymore considered valid models. Earlier the string type of data was accepted and converted into dates when model was loaded (for in-memory models) or in SQL queries (in Snowflake models).
* 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).
</div>


'''Fixed issues:'''
The following query can be run in the [[Navigation_Menu#Expression_Designer|Expression Designer]] (with System administrator user) to list models where the events datatable timestamp column type is string:
* D-12586: Scripts using client-side import with older version of QPR ScriptLauncher didn't work.
<pre>
* D-12597: QPR ScriptLauncher was not sending heartbeats during import, which might have stopped the script prematurely.
Models.Where({
* D-12589: Pressing Add measure/Add dimension button crashed chart.
let timestampColumn = _.Configuration?.TryGetValue("Datasource")?.TryGetValue("Events")?.TryGetValue("Columns")?.TryGetValue("Timestamp");
* D-12558: In chart settings, setting expression to "(none)" gave error.
return First(_.EventsDatatable?.Columns?.Where(Name==timestampColumn))?.Datatype == "String";
 
}).(Name + " (id: " + Id + ")");

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

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
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.
For Snowflake dashboards, table actions to [[QPR_ProcessAnalyzer_Table#Table_actions|set dashboard variables]] now set the variable values in the [[Stringified_Value_Format|stringified format]] instead of as raw values. This makes the variables set by table actions compatible with the [[Chart_Linked_Settings|linked settings]] which also use the stringified format by default for the Snowflake models.
 
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:
<pre>
let removedAnalyses = Flatten([0,8,9,10,13].(["'AnalysisType','" + _ + "')", "'AnalysisType', '" + _ + "')"]));
OrderByDescending(Flatten(Projects.Scripts).Where({
  let scr = _;Sum(removedAnalyses.{let num=_;scr.code?.Contains(num)})>0;
}),LastRunStart).(Project.Name + ": " + name + " (last run: " + (LastRunStart ?? "N/A") + ")");
</pre>

<div style="border:1px solid #dfdfdf;padding:0.5em 1em 0.5em 1em;background-color:#E7EAEC;margin:10px 0px 0px 10px;">
*Changed Snowflake charts to store [[QPR_ProcessAnalyzer_Table#Table_actions|variable change actions]] in stringified format to make them compatible with linked settings. (B-08587)
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.
*Backend support for [[Filtering_in_QPR_ProcessAnalyzer_Queries#Object-centric_filter_rules|object-centric filter rules Disabled flag]]. (B-08611)

Latest revision as of 09:49, 5 November 2025

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

Next Release: QPR ProcessAnalyzer 2025.7 (planned 2025-11-11)

See roadmap for next release features and fixes

Latest Release: QPR ProcessAnalyzer 2025.6 (build 10690) (released 2025-10-01)

New features presentation: QPR_ProcessAnalyzer_2025_6.pdf

Known issue: If the DefaultUiLanguage system configuration is not defined, users who haven't changed their own language, are unable to login. To prevent this problem, please ensure the DefaultUiLanguage is defined. The next release will fix this issue (D-14706).

Content-Security-Policy (CSP) HTTP header has been updated to enhance security by implementing more restrictive settings. The following directives have been added:

  • object-src 'none'
  • frame-ancestors 'self'
  • form-action 'none'
  • base-uri 'none'
  • worker-src blob:

These new restrictions may affect usage that has previously been possible. For example, with the new settings, QPR ProcessAnalyzer can be embedded to a website only within the same origin. For detailed instructions on embedding QPR ProcessAnalyzer on a different website, please refer to this quide. Additionally, for information on modifying the CSP settings, see documentation for security hardening.

In the QPR ProcessAnalyzer 2025.6 Native App, the release version number is not displayed correctly in the User Settings dialog. This omission does not have any other complications. QPR ProcessAnalyzer 2025.6 is the only release with this issue, making it possible to identify this release despite the missing version number. This issue is specific to the Native App only. The next release will fix this issue (D-14703).

QPR ProcessAnalyzer 2025.2 (build 9410) (released 2025-03-05)

New features presentation: QPR_ProcessAnalyzer_2025_2.pdf

Detection of models with incomplete datasource configuration has been improved, and now models where the event timestamp column type is string, are not anymore considered valid models. Earlier the string type of data was accepted and converted into dates when model was loaded (for in-memory models) or in SQL queries (in Snowflake models).

The following query can be run in the Expression Designer (with System administrator user) to list models where the events datatable timestamp column type is string: 

Models.Where({
	let timestampColumn = _.Configuration?.TryGetValue("Datasource")?.TryGetValue("Events")?.TryGetValue("Columns")?.TryGetValue("Timestamp");
	return First(_.EventsDatatable?.Columns?.Where(Name==timestampColumn))?.Datatype == "String";
}).(Name + " (id: " + Id + ")");

For Snowflake dashboards, table actions to set dashboard variables now set the variable values in the stringified format instead of as raw values. This makes the variables set by table actions compatible with the linked settings which also use the stringified format by default for the Snowflake models.

New features

  • Snowflake warehouse can be specified for each model allowing to use optimal type of warehouse for different sizes of models. (B-08610)
  • Home screen has been removed, and Workspace has new card layout and other UX improvements. (B-08541)
  • Added filter description field to filter properties dialog. (B-08451)
  • Removed event type existence check from charts, so that non-existing event types are allowed. (B-08585)
  • Snowflake Native App configuration data can be backed up to a snapshot and restored. (B-08591)
  • Improved detection of invalid models by adding CheckModelValidity function returning model validation errors. (B-08426)

Fixed issues

  • Prevented following error in Snowflake dashboards: Object "qprpa_dt_cache_..." already exists when creating a cache table. (D-14348)
  • In-memory chart "Cases filtered by attribute" didn't work for date type of attributes. (D-14387)
  • Fixed issue where each dashboard element resize made element width or height increase when chart margin was more than zero. (D-14361)

  • Backend support for object-centric filter rules Disabled flag. (B-08611)
  • Implemented Entity Framework based database initialization and migrations. (B-08566)
  • Added support for following Entity Framework database providers: SQL Server (full), Snowflake Hybrid Tables (experimental), PostgreSQL (experimental). (B-08581)
  • Frontend components have been updated. (B-08597)
  • Backend components have been updated. (B-08596)
  • Translations have been updated for release 2025.2. (B-08607)
