QPR ProcessAnalyzer Release Notes

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

Next Release: QPR ProcessAnalyzer 2024.8 (planned release date 2024-12-10)

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

External content component doesn't allow to embed websites from other origins than the QPR ProcessAnalyzer server hostname. 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.

Latest Release: 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
QPRPA_UDF_BPMN_IS_CONFORMANT
QPRPA_UDF_BPMN_CONFORMANCE_VIOLATIONS_FLOWS

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

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.

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

Limitation for the maximum amount of data (B-07636) causes a behavior change in in-memory charts that have the Maximum rows settings empty and have the sorting defined. In certain cases, the order in which measures are evaluated changes (due to an internal performance optimization). If there are custom expressions that define variables, the variables may not be available in other measures anymore. As a resolution, either redefine the variables in those measure expressions or add those measures secondarily to the sorting.

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-08150: Added setting Apply chart filters first to determine whether chart filter rules or dashboard filter rules are applied first when chart queries are filtered.
B-08091: When filtering charts in Snowflake, case attribute filter is created instead of case id filter.
B-08091: New setting to define whether cases or events are filtered by default.
B-08091: New preset "Looping paths" to detect whether there are repeating patterns of events.
B-08091: Duration between events calculation ignores negative durations in Snowflake.
B-08091: Chart loading animation has been renewed.
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).
B-08123: Translation updates for 2023.7.
B-08092: Updated backend components.

D-13869: Export as CSV button didn't work in the datatable contents dialog when dialog was still loading.
D-13872: Main progress spinner had unnecessary small scrollbar on top right.
D-13863: In the REST API method GET /api/users, password field (that has always been null) has been removed.

QPR ProcessAnalyzer 2023.6 (build 3847) (released 2023-10-17)

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.
