Duplicate invoice error not working every time

[Former Member]

Dear all,

We have some problems with duplicate invoice check.

We activated transaction OMRDC with following options:

- Inv. Date,

- Company code,

- Reference.

But some times we have duplicate invoice in the system. The vendor have been activated for duplicate invoice check (transaction XK03).

Any idea?

Thanks for your help.

Please check the following settings and entries were made in your system,

1) Check the indicator 'Chk. double inv' in the vendor master record

2) Check whether the indicators ’Check co. code', 'Check Reference', 'Check Inv. Date' in OMRDC were set for your company code

3) Check the reference document number was entered in MIRO.

Note: In materials management, the system only checks for duplicate invoices if you enter the reference document number when entering the invoice.

Reference: SAP note 305201

There are certain rule/criteria to use the restriction of duplicate invoice.

OMRDC is used for MIRO transaction and the option 'Chk double inv.' is checked when invoice is posted from FI transaction (like FB60).

First you need to check the changes log for these both tick. Then check when message are set as error M8462 / M8108 / F5117. Additionally check this KBA document 1785169 - Duplicate Invoice Check along with there are many others KBA document exist in service market place.

Hi,

You need keep Reference number field as mandatory in "RE" document type in   t.code OBA7 and

set Error  for messages M8-471,M8-108 & M8-462 in t.code: OMRMin and also  t.code: OBMSG

Can you show us an example of such duplicate invoice. (showing the data of the chosen options from OMRDC of both invoices) A computer is petty, even a space is a character
