System Response

The items in the current reversal run were not all reversed, or were not
transferred to a reversal distribution lot. The total of the remaining
items in the distribution lot means that the payment assignment cannot
be adjusted.
This situation occurs in the following circumstances, for example:
Payments on account and disbursements are generated by the distribution
lot and the balance of the original distribution lot results in a pay-in
amount.
The items for reversal were not all reversed or were not included in a
reversal distribution lot.
The remaining items in the lot result in a disbursement amount. This
means the payment assignment cannot be adjusted, so that the system
deletes it.

How to fix this error?

Assign an aggregated outgoing payment on account document to the
distribution key. You may have to select the <ZK>Post Distribution Lot
</> indicator so that the system allows this.
Reverse the distribution lot items that have not yet been reversed, or
transfer them to a reversal distribution lot.
