When Navigating to K2 Workspace > Process Overview > Process > Click on View Flow, the below error occurs:
24129 A database error occurred: Ambiguous column name 'ProcSetID'.
By reviewing the SQL Profiler trace you will notice that the below query:
exec [ServerLog].[kPSIDFromPIID] @PIID=''Number' will be present on SQL trace.
By executing this directly in SQL Query the same error will be generated.
Msg 209, Level 16, State 1, Procedure kPSIDFromPIID, Line 8
Ambiguous column name 'ProcSetID'.
Please note that this is a K2 Database StoreProc
K2 database modification is not allowed as it might leave the environment in an unsupported state. This must only be done with the assistance of, or when instructed to do so by K2 Support.
By doing a compare of a clean K2 Database StoreProc and the problematics storeproc you will notice no differences but when investigating the below table it will be discovered that the ProcInst Table had a duplicated entry of ProcSetID column.
SELECT * From [ServerLog].[ProcInst]
Should the results display an extra column, it would indicate that this is causing the error. To resolve this issue, direct database modification will be required.
Please log a K2 Support Ticket on the K2 Customer Portal for assistance in resolving the issue.
