I want to make mandatory for "PRPS-USR01" field from CJ20N transaction.
If SAP_PRPS-usr01 is initial.
Message e000(ZMNR) with 'hai'.
In this user exit EXIT_SAPLCJWB_001. This above logic is working after you keep cursor in USR01. If you do not go to USR01, then it is not mandatory. You can still save it without any value in the field. If there is no entry, then it gives an error message and does not allow you to go out it , unless the field is filled from the drop-down list.
How can i made it mandatory??
pls guide me
