Can someone please help me understand the difference between document type RK & RERK?
G Lakshmipathi replied
RK Invoice Correction Request would be used when there is some pricing issue in the original billing document and the changes you make will have only financial impact and not related to quantity changes in case of returns. But with RERK document type, it is quite possible.
You need to maintain copy control as follows:-
F2 > RK
RK > RERK
RERK > LR
RK > G2
Needless to mention, some customization would be involved for new goods return request
