InvalidReferenceException occurs though pc_work_fed col in FCMR

SA-102454

Summary



InvalidReferenceException is generated frequently in the Pega logs though the database schema has the DATA.pc_work_fed column in the Federated Case Management Repository (FCMR) database. This occurs when a custom report of Work-Federated is executed.


Error Messages

An error occurred during resolving the report definition - InvalidReferenceException    .pxCreateOpName    Unexposed properties cannot be selected for classes mapped to external tables


Steps to Reproduce



Create a report in the Work-Federated class that has references to the .pxCreateOpName property.


Root Cause



The user attempted to resave the Data-Admin-Database-Table (DADT) rule. As the report definition displays results and the exception only occurs while executing the report definition, this is a false exception. The code that determines if the property is exposed, is incorrect. This is because a call to the pr_read_from_stream out-of-the-box User Defined Function (UDF) must occur if the properties are unexposed, and which did not happen.


Resolution



Perform the following local-change:

Disable the 'Report on descendant classes' option.
