What causes this issue?

Provisions for accrued rebate income have been determined in the course
of the price determination process (condition type is relevant to
provisions for rebate income).
These were not posted at the time of goods receipt because the account
key is missing from the calculation schema for the supplier.

System Response

Since no provisions for income were posted, no business volume update
has been carried out either.

How to fix this error?

Please maintain the account key for provisions in the calculation schema
for the supplier. If necessary, contact the person responsible for this
in your enterprise.
You may have to cancel already posted material documents in order to be
able to post and update the provisions for rebate income ("Detailed
statement" function for the rebate arrangement).
The relevant document from the fiscal year &V2& has the document number
&V1& (item &V3&). The rebate arrangement is &V4&.
Please note:
Provisions for accrued rebate income are posted at the time of goods
receipt. However, in the case of rebate arrangements entered prior to
Release 4.0, updating of such provisions does not take place until the
time of invoice receipt. If necessary, please also cancel the relevant
invoices.
