Duplicate Invoice PROBLEM with IDOC

[Former Member]

Hi,

I have duplicate invoice problem at my client place. I have followed all required steps in MM config for duplicate invoice check in OMRDC tcode by checking "refer no" field and checking "double invoice check" in vendor master.

When I'm trying to post an invoice with already existing "reference number", system is stopping by giving a msg "a duplicate invoice has been found under XYZ account doc". But when I'm trying to do the same with IDOC for that particular vendor a new invoice is posting with already existing "refer no". In short system is posting a duplicate invoice when I'm trying to post it through IDOC.

Can anyone please suggest where should I look up so that a "duplicate invoice" should not get posted when processing though IDOC or am I missing any other steps in IDOC configuration.

Thanks in Advance,

Sara.

Hi Santosh,

Thanks for your response. Honestly speaking I do not have much knowledge on IDOC(EDI). Can you please explain in detail on how to have "checking control at interface level"..like how should I approach on this (steps).

Thanks,

Go.

When u send idoc outside of SAP sustem , next system which acts as interface can have program for checking to invoice field..

U can trigger no of idocs from SAP--but interface can have control to accept that idoc..

This is inbound IDOC , coming from a vendor(invoice), creating invoice(Tcode MIRO) through IDOC . I guess as per your saying I need to have check control at the interface so that if its a duplicate invoice it should not be posted for payment. Please correct me if I'm wrong.

Thanks again,

Go.

Hi ,

You can configure user exit EXIT_SAPLMRMH_015 in enhancement MRMH0002 so

that the system checks for a duplicate invoice when the EDI invoice is

entered.
