I need to validate Network header with a condition on the prerequisite that chek the number of the WBS that assigned to the network header.
for example: Check validation only if the WBS number that assigned to the network header begin with the characters "WBC ". however, the field that is option to WBS in structure CAUFVD is data type NUM8 (PSPEL for example). I wonder if there is any way to use the CHAR24 data type (POSID) or as alternative to convert PSPEL to POSID, in the validation screen without using the exit?
Thanks in advance
