Values for manual condition types can not be changed at the time billing
I have one pricing procedure for sales order and billing doucment. All those condition types in pricing procedure are set as manual ans as fixed value. Now after entered values for each condtion types in sales order, system should not allowed to change values at the time of creating billing document with reference to that sales order, so how can i resolved this issue?
Is there any standard configuration available in system or we have to write logic for that, and if required to write logic then which can be used either Userexit for billing documents or can we use any routine?
FYI, here sales order equals my provision request and billing equals my provision memo and thats why we do not required outbound delivery inbetween.
Quick response highly appreciated...........
