Dear All,
The following logic has worked in my case for level 1 WBS.
Pre-requisite
PRPS-STUFE='1'
Check
PRPS-POSID :13-14: = '00'
Message
Error message
Similar logic is working for other levels also.
I thank everyone for their support in helping me resort this issue.
I would like to appreciate Sarath for bringing out ABAP solution for this issue which i suppose would work in this case , but I would like to go ahead with standard configuration available for validation in PS module.
Closing this thread.
Thanks again .
Regards,
Vishal
