Avoid duplication of material number in Sales Order.

[Former Member]

Hi all

I want to restrict the user for entering the duplicate Material number while creation of Sales Order . I have done the changes in Program MV45AFZZ IN FORM USEREXIT_SAVE_DOCUMENT_PREPARE, but was able give warning message for duplicate material no.

If I set these message to error , the user has to come out of the sales order ,as it doesnot even allow to save.

Can any body guide for proper steps to follow to avoid the duplication of the material while creating the Sales Order

Thanks for yr suggestion , the logic of tracing the duplication is done in above said form of user exit and working as desired.

Hi,

Use userexit USEREXIT_MOVE_FIELD_TO_VBAP instead and check entries in internal table XVBAP.

Thanks,

If your ABAPer has written the User Exit, then he can as well do what you want. Ask him to do it, it should be a small code.

Happy SAPing.
