QPR ProcessAnalyzer Release Notes

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

Next Release: QPR ProcessAnalyzer 2022.7 (planned release date 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(%'

Features:

• B-07378: Frontend support for the query "limited mode".

• D-12561: Chart settings content was incorrectly drawn outside of the chart dialog.

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

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)

This release has the following issues which will be fixed in a hotfix (to be released soon):

• 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 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") + ")");

Features:

• B-06524: Search dialog for finding and selecting multi-select items.
• B-07173: CSV file importing supports date columns for row matching.
• B-07277: Query timeout for dashboards.
• B-06921: Expression language: For loop.

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 2022.2 (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.

Additional release for QPR ProcessAnalyzer 2021.9 (build 709) (released 2021-12-20)

This release has brought back SQL Server 2014 support.

Features:

• B-06489: Restore support for SQL Server 2014.
• B-06257: Add new SAP data extraction connector library SAP NetWeaver RFC (preview feature).
• B-06443: Snowflake availability status is added to /api/serverinfo.

QPR ProcessAnalyzer 2021.9 (build 700) (released 2021-12-14)

Starting from QPR ProcessAnalyzer 2021.9, ScriptLauncher uses Web API instead of legacy WCF API, and thus also the 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.

When taking into use the Web API based ScriptLauncher, the ServiceUrl setting in the ScriptLauncher configuration file needs to be set differently: Previously it was enough to specify the server name (e.g. https://processanalyzer.onqpr.com), but now also the application path needs to be specified (e.g. https://processanalyzer.onqpr.com/qprpa). This issue will be resolved in upcoming release.

Starting from QPR ProcessAnalyzer 2021.9, support for SQL Server 2012 and SQL Server 2014 has been dropped. See more in system requirements.

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:

• --#GetAnalysis command in SQL scripting: If there are scripts using that command, replace them with the new --#RunQuery which uses the expression language to query data.
• 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 /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 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.

When installing 2021.9 server, note that there is a change in the web.config file, as httpRuntime element includes now targetFramework="4.7.1" attribute. Also, QPR ProcessAnanalyzer ScriptLauncher web.config has changed, as ConnectionType is now WebApi instead of Service.

SQL scripting commands that create datatables and temporary tables, use now specific column data types (such as NVARCHAR(MAX), INT, FLOAT, DATETIME2 and BIT) instead of SQL_VARIANT. This may affect SQL commands that have relied on the SQL_VARIANT column type. For example, in joins there may be mismatches between data types, requiring explicit type conversion.

Features:

• B-03221: Flowchart has been renewed.
• B-06378: Old flowchart has been removed.
• B-06317: --#runQuery to run expression queries in SQL scripts.
• B-06343: Bottleneck Flows preset is now sorted based on case counts and other visual improvements.

• B-06427: Append function for SqlDataFrames corresponding to UNION ALL in SQL.
• B-06397: Backend support for modifying Snowflake stored datatables.
• B-06408: Translation updates for 2021.9.
• B-06412: CalcTester and ScriptLauncher are combined.

QPR ProcessAnalyzer 2021.8 (build 614) (released 2021-11-02)

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.

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.

Additional release for QPR ProcessAnalyzer 2021.6 (build 474) (released 2021-08-25)

Notes:

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.

QPR ProcessAnalyzer 2021.4 (build 328) (released 2021-05-18)

Notes:

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.

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).

Tables used in dashboards are updated to the next generation of Syncfusion JS2 components. The 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/.

Starting from QPR ProcessAnalyzer 2021.4, the 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).

There is a new step in the QPR ProcessAnalyzer server installation instructions for allowing large process mining models: .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.

QPR ProcessAnalyzer 2021.1 (build 163) (released 2021-01-18)

Features:

• 308096: New function "EventLog" to expression language to explicitly define preprocessings.

Fixed issues:

• 219612: Opening models dropdown list jammed UI when there are lot of models.
• 219495: Improve error message when trying to change login name to already existing.

QPR ProcessAnalyzer 2021.1 (build 156) (released 2021-01-12)

Notes:

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 Chart presentation object, which supports many layouts such as 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.

Data types of the datatables and temporary tables created by the --#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.

Features:

• 308075: Chart data point colors can be defined using conditional formatting.
• 307816: Datatables to workspace (part 1).
• 308076: QPRLibraries migration to Syncfusion JS2 (part 4).
