Dear all,
I have been able to make a field mandatory on a selection screen. This is field username. However, the system does not check if the user exists.
What I have done is made a copy of the program behind LX16: RLINV015
Now I have ZLX16 and ZRLINV015
I know the SAP users are found in tabel USR02, so I have added this table under data definition where the other tables are mentioned.
How do I enforce that only existing usernames are entered?
Thanks,
Nick
