Check user name on selection screen


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?
