We are having problems with a process GEL script and query (used in a portlet) after upgrading to 15.4. I have attached the GEL script and NSQL query script for reference.
use of WM_CONCAT function has been removed from Oracle 12c.
CA PPM 15.3 and above will only support Oracle 12c or higher, and since 12c, Oracle have now removed the WM_CONCAT undocumented feature from their product.
Swapped out the WM_CONCAT function with LISTAGG. The queries and GEL script are running fine.
