Hello all !
We are upgrading from portal 7.0 to 7.4.
Our back end remains ECC 6(EHP 6).
When leave is applied from portal 7.0, the workflow WS12300111 is getting triggered.
However, when leave is applied from portal 7.4, the workflow is not getting triggered and PTREQ_HEADER is populated with correct values except WORKIEM_ID field which gets populated with value 000000000000.
Dialog tasks and workflow header is set to general task. Functional configuration for leave request is correct.
Visualization parameters for both the tasks are maintained as seen below : 
SICF services for leave request are active.
However, workflow is not triggering when leave is applied from portal 7.4. Please suggest.
Regards,
S.Suresh.
