Unable to create Programs due to pyWorkID issue



We have recently upgraded our Production and Test environments to NBAM 7.11/PRPC 7.1.6. Post this, errors have been seen when running programs, but only sporadically and only in the Production environment. The error states that pyWorkID from the Data- class cannot be ‘seen’. This is not true, the Class Hierarchy is correct. It is possible to create an Activity in the Event Class that also does not ‘see’ the Property, meaning it is not an NBAM issue, but instead a core PRPC issue.
When the errors occur – and it does not impact all Programs, just a small percentage – Saving and Revalidating the Property (pyWorkID) fixes the issue.

Steps to Reproduce

Create a program in NBAM

Root Cause

The root cause was not identified as this issue occurred only 2 times. Performing a Save and Revalidating of the pyWorkID property has resolved the 2 occurrences that were encountered. We crossed checked PRPC cache synchronisation issues related to HFIX-9472 and confirmed that the required parameters are set correctly and all NBAM hotfixes are installed and found to be correct.


Saving and Revalidating the pyWorkID in Data- class resolves the issue.
