Hi Joao,
yes..that is a possible answer..
while creating set..for authorised users, I am trying to create a data set (T.code - GS01), so those user name mentioned in the set can be given authorisation. But I tried giving table BKPF and field name as USNAM.
However, its not accepting. can u pls mention the appropriate table and the field name that need to be mentioned in the set. So these set can be linked to GGB0.
Pls note- I have created other set that map company code-Vendor etc..
