When using the transaction Migo (create), the user can enter a certain characteristic through -> batch -> classification for each position. I have to check that the input code is not already used in another posizion.
I found the Badi CACL_VALUE_CHANGE, but at this point I have only the characteristic of a single position.
Does anybody know the internal table which stores the characteristics and at what point can I go to check them?
I also found these internal tables IZH, AMM and ZM, but at the time of final check, they are not available.
I thank you in advance
