SAP Note 26137 - CO13/CN29/IW45: Posting in a closed period

Symptom:

When cancelling a completion confirmation, the actual costs are determined and backflushing takes place for the posting date which was taken from the completed confirmation. If the cancellation takes place at a later time then the posting period can be closed already at the posting date. It is necessary to close the posting period(s) again.

Cause and prerequisites

The posting date for the confirmation cannot be changed when cancelling.

Solution
If the posting period for the posting date is closed, then the posting date can be changed when cancelling. A warning informs the user that the posting date falls in a closed period. However, the date need not be changed, it can be posted in the already closed period.
If the posting date is changed, the actual costs determination can produce a different result when cancelling from that when entering. The reason for this is the different rates of activity types for the changed posting date.
The consequences of this is that the order is credited with costs that are either too high or too low.
