How To Fix KD579 - Differing posting period in reversal and settlement to be reversed

KD579 - Overview

• Message type: E = Error

• Message class: KD - CO Settlement

• Message number: 579

• Message text: Differing posting period in reversal and settlement to be reversed

What causes this issue?

The reversal of the settlement is to be posted in posting period &v1&/
&v2&, but the settlement to be reversed was posted in period &v3&/&v4&.
Such a reversal does not always make sense from a business point of view
(see SAP Notes 359814 and 421493).

How to fix this error?

Check the posting period of the reversal, and use the posting period of
the settlement to be reversed.
To enable reversal in a different posting period, the message can be set
as an information message (type I) using transaction <DS:TRAN.OBA5>OBA5
</>, or else be completely deactivated.
