SAP Note 21496 - Down payment for order not credited during settlemt

Symptom:

If down payments were assigned to a CO object that was subject to settlement (e.g. order, WBS element, network), they are updated on the CO object (COEP with value type 12), but in the settlement (usually to AuC = asset under construction) no credit posting is created.
The down payment is correctly posted on the settlement receiver (AiB).

Cause and prerequisites

During the posting, the CO object is not really debited with a cost element. The down payment line item with value category 12 does not appear anywhere in the cost accounting. Consequently, no credit is required.
The settled amount is only updated internally in the settlement tables (COSPD, COEPD) as settled.
The offsetting entry for the settlement receiver (AuC) is posted on the clearing account for down payments defined in the account assignment customizing of the asset under construction.
