Latest Release: QPR ProcessAnalyzer 2024.1 (build 4784) (released 2024-01-10)

Known issue: In Big data chart, some measures, dimensions and columns have the filtering option missing. The issue concerns for example Duration between events, Path starting/until between specific events, and Cases where event occurs before other selections. Workaround is to set the filter in the chart json settings: the filter can be configured to another expression and copied to the correct expression.

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 (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.

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.

QPR ProcessAnalyzer 2023.7 (build 4326) (released 2023-11-28)

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-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).

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.

QPR ProcessAnalyzer 2023.1 (build 1433) (released 2023-02-07)

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

"preset": "RootCauses"

and the comma from the preceding line.

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 --#GetAnalysis command), and thus needs to be changed to the --#RunQuery command (see the examples page how each legacy analysis can be replaced). Note that the legacy analyses removal don't affect the dashboarding functionality.

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") + ")");

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.

Features:

• B-06997: Expression-based filter rules for Snowflake dashboards to allow versatile filtering and filtering from custom expressions.
• B-07383: Improvements to linked settings to allow binding to variables, tags and filter rules (more information).

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(%'
