I have to do the enhancement for VA01/VA02/VA31/VA32, where the header and item level partner defintion should be editable. By default it must be having the appropriate value from the KNVP table.
Again the field KNREF should be modifiable by using this transaction.
Pls. can you tell me what is the way to accomplish it. I told to make a change in MV45AIZZ and MV45AFZZ.
If I am not wrong then have to change the screen attribute in MV45AFZZ, where KNREF is updatable and have to save that value in VBPA-KNREF by using the MV45AIZZ.
Pls. tell me wht would be the screen no. and suggest if dere is any other way or not?
