Transaction IW32 - EXIT - Order Position

Hi!,

I´m having a trouble with IW32 transaccion, I have to validate the order positions by position number, if the position number has permition to be modified, nothig happend but if it hasn´t permition i need to display an error message informing that u can´t modify the position, and then change the modified field by the old one.

I´m using the BADI: IW01_ORDER_BADI

METHOD: CHANGE_COSTRELEVNCY

In that method I can validate by position and I have in the Params The OLD and the NEW structure containing the position. My problem is that i cant set the vlaue in the screen, I need to replace the modified item in the screen by the old one and show the error message.

ok thats all, i hope u can understand the post, i´m an argentinian practicing english.

Bye Bye an thanx!!!
