Invoice correction request / pricing

Hi all ;

I create a invoice correction request with referance an invoice while i get all condition types in sales order like belowed.

ZFIY : Price , ZI01 : Discount , ZKDV : Tax

I want to change it this pricing with ;

Clear discounts and modify ZFIY with net price as same as ZFIY : 4,65 TRY.

To get it , i work on user-exit -->

• USEREXIT_PRICING_COPY (module pool SAPLV61A, program RV61AFZA)

But , i can not achieve it. Is there any ways to solve problem ?

Regards.
