I have to update the field assignment (ZUONR) when I post an accounting document in FN8X.
I was looking for information about it and I found documentation about the user exit: EXIT_SAPLFVN_BUS_OPERATION_102
The ABAP made a brake point in the INCLUDE ZXFVNBOU02 however the program didn't stop.
Somebody knows if this user exit is helpfull? I have to activated this user exit? where?
Could you recommend other way to update the field assignment?
