QPR ProcessAnalyzer Release Notes

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

Next Release: QPR ProcessAnalyzer 2023.1 (planned release date 2023-02-07)

Following legacy analyses have been removed: Cases (analysis number: 5), Events (6), and EventTypes (7). This functionality may be used by SQL scripts (in --#GetAnalysis command), and needs to be changed to use the --#RunQuery command. Note that this change doesn't affect the functionality in the QPR ProcessAnalyzer web UI.

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 = [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;
}),LastRunStart).(Project.Name + ": " + name + " (id: " + id + ") (last run: " + (LastRunStart ?? "N/A") + ")");

Features:

Latest Release: Additional release for QPR ProcessAnalyzer 2022.8 (build 1397) (released 2023-01-11)

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.

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)

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.

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.

QPR ProcessAnalyzer 2022.7 (build 1331) (released 2022-11-15)

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:

SELECT * FROM [PA_UI_ELEMENT] WHERE [UIE_PROPERTIES] LIKE '%SendEmail(%' OR [UIE_PROPERTIES] LIKE '%CallWebService(%' OR [UIE_PROPERTIES] LIKE '%ImportOdbc(%' OR [UIE_PROPERTIES] LIKE '%ImportOdbcSecure(%' OR [UIE_PROPERTIES] LIKE '%DeletePermanently(%' OR [UIE_PROPERTIES] LIKE '%Restore(%' OR [UIE_PROPERTIES] LIKE '%TriggerNotifications(%' OR [UIE_PROPERTIES] LIKE '%CreateDatatable(%' OR [UIE_PROPERTIES] LIKE '%AddColumn(%' OR [UIE_PROPERTIES] LIKE '%DeletePermanently(%' OR [UIE_PROPERTIES] LIKE '%Import(%' OR [UIE_PROPERTIES] LIKE '%Merge(%' OR [UIE_PROPERTIES] LIKE '%RemoveColumns(%' OR [UIE_PROPERTIES] LIKE '%RenameColumns(%'

Additional release for QPR ProcessAnalyzer 2022.6 (build 1262) (released 2022-10-19)

This release contains fixes to following major issues:

• 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).

Fixed issues:

• D-12586: Scripts using client-side import with older version of QPR ScriptLauncher didn't work.
• D-12597: QPR ScriptLauncher was not sending heartbeats during import, which might have stopped the script prematurely.
• D-12589: Pressing Add measure/Add dimension button crashed chart.
• D-12558: In chart settings, setting expression to "(none)" gave error.

QPR ProcessAnalyzer 2022.6 (build 1259) (released 2022-10-05)

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 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.

Following script can be run in the Expression Designer to show whether there are scripts in the system that likely use the removed analyses:

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") + ")");

QPR ProcessAnalyzer 2022.5 (build 1179) (released 2022-08-24)

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 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.

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 script can be run in the Expression Designer to show whether there are scripts in the system that likely use the removed analyses:

let removedAnalyses = Flatten([1,4,17,21,22,23,24].(["'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") + ")");

QPR ProcessAnalyzer 2022.3 (build 925) (released 2022-04-20)

In Workspace, dashboards and scripts cannot be created anymore to the Workspace topmost level. All existing dashboards and scripts in the topmost level are moved to a new project named System, where administrators can access them. If dashboards and scripts are moved away from the Workspace level before the QPR ProcessAnalyzer 2022.3 update, the System project is not created.

In QPR ProcessAnalyzer 2022.3, the legacy SAP NetWeaver RFC library for SAP connections has been removed, and now SAP connections use the new SAP NetWeaver RFC library. Also the related SapProvider setting in the SAP import command is not anymore in use.

QPR ProcessAnalyzer 2022.2 (build 854) (released 2022-03-09)

SAML 2.0 authentication has been renewed, changing related urls as follows: SAML authentication is initiated from path /saml2 (previously it was /api/saml). In addition, the redirect back url is now /saml2/acs (previously it was /api/samlsignin). These changes need to be made to the identity provider and taken into use during the QPR ProcessAnalyzer 2022.2 update. In addition, the redirection to the SAML authentication initialization path, that has possibly been set to IIS, need to be changed.

SAP connector has been changed to use the newer SAP NetWeaver RFC Library provided by SAP. Due to this change, additional installation steps for QPR ScriptLauncher and QPR ProcessAnalyzer Server need to be done. The changes only affect environments where the SAP connector is enabled.

The WCF API has been removed from QPR ProcessAnalyzer 2022.2. Before updating, all customized integrations and other solutions that use WCF API need to be converted to use Web API. Note that there may also exist scripts that contact the WCF API using the --#CallWebService command. The used API can be distinguished from the url: if it contains "/MainService.svc" the connection is to the WCF API and changes are required. Note also that if QPR ProcessAnalyzer Excel client has still been in use, from now on it will not work.

Due to the WCF removal, installing QPR ProcessAnalyzer Server is now easier, as there is only one web.config file (i.e., no separate web.config files for http and https). Note also that the contents of the web.config file is changed, so settings contained by the file need to be migrated manually.

Salesforce connector has been changed to use Salesforce REST API, and the API version is changed from 38 to 54. Due to the change, there might be slight differences in the Salesforce connector behavior.

Features:

• B-06441: Snowflake stored datatables and models can be managed in Workspace.
