F-41 vs MIRO - duplicate credit memo not checked in MIRO


We used to do F-41 for credit memos to our suppliers. We recently decided to use MIRO instead. We realized that the system does not warn the user anymore when he tries to enter a duplicate credit memo.

In F-41, when we enter 2 credit memos with the same information:



-Company code

-Gross amount of the invoice

-Reference document number

-Invoice document date

This error message appears: check whether document has already been entered under number ADM XXXXXXXXX XXXX.

Using MIRO, we don't get this error message anymore. We would like this message to appear also in MIRO.

Is it a functional issue?

I checked the master data of the supplier, and the check box Chk double inv. is checked.

Is it a configuration issue?

I checked t-code OMRDC and the 3 check box are marked with a check (check co. code, check reference, check inv. date).

I looked at SAP help and it says: When you enter credit memos or subsequent adjustments, the system does not check for duplicate invoices. I'm not so sure what this statement means....

Many thanks for your help.
