Duplicate invoices verification not working in FI

[jan_turek]

Hi all,

We experienced the problem with duplicate invoices posting check in FI (not logistics).

The indicator Chk double inv. (LFB1-REPRF) is checked in Vendor master data. However, we are still able to post several documents with these fields identical: BUKRS, LIFNR, WAERS, XBLNR, WRBTR, BLDAT in FB01 or FB60.

The message F5 117 should appear but it does not - when I check OBA5 for area F5 the message is not here at all.

What could be the problem?

ECC 6 EHP 6 SAPKH60605

thanks to all

Hi Marko,

All keys are 31. However, at least in one case I can see that the was an invoice reversal - in this case the check does not work.

Users have to test more cases to see under which circumstances the message appears and when not.

@vijay anadhan: all 3 indicators checked.
