MN579 - Overview

• Message type: E = Error

• Message class: MN - Message class for subsequent settlement (Purchasing)

• Message number: 579

• Message text: Not possible to update busn. vols. for reb. arr. (cond. record settled)

What causes this issue?

Although settlement accounting has not yet been carried out for rebate
arrangement &V1&, the condition record for the document conditions has
been assigned the status "Settled".

System Response

Since no further settlement accounting is planned for the condition
record, no supplier business volume data can be updated.

How to fix this error?

This situation should not normally arise (program error). You should
therefore contact your system administrator.
You can also proceed as follows:
Check whether the supplier business volume data is to be taken into
account.
If so, cancel the settlement document(s) relating to the condition
record. This will cause the status of the condition record to be reset
to "Active".
Update the cumulative business volume data retrospectively using one of
the functions provided for the purpose.
Using the relevant functions/reports, check whether there are any
further open transactions (purchase orders, goods receipts, supplier
invoices).

MN579 - Details

• The SAP error message MN579 indicates that the system is unable to update business volumes for a rebate arrangement because the condition record has already been settled. This typically occurs in the context of rebate processing in SAP, where the system is trying to update or adjust business volumes related to a rebate agreement, but the condition record associated with that rebate has already been settled, meaning that the financial transactions related to that rebate have been completed.
  
  Cause:
  
  Settled Condition Record: The primary cause of this error is that the condition record for the rebate arrangement has already been settled. Once a rebate is settled, the associated business volumes cannot be modified or updated.
  Incorrect Processing Sequence: The error may also arise if there is an attempt to process or update the rebate arrangement in an incorrect sequence, such as trying to adjust volumes after settlement.
  Data Inconsistencies: There may be inconsistencies in
