How To Fix MN338 - Offsetting of income effected with different account key

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 338

• Message text: Offsetting of income effected with different account key

What causes this issue?

Account key &V1& has been entered against condition type 'S000'
(settled income). This differs from account key &V2& of the condition
type &V3& requiring settlement.
Under certain circumstances, this may lead to different postings of the
two amounts (total rebate income, income from previous settlements) in
Financial Accounting.
If income from previous settlement runs (e.g. from interim or partial
settlements) is to be offset against the total rebate due in the course
of settlement accounting with respect to a condition record, the income
relating to the condition record is initially identified in the price
determination data. This must be reduced by the deduction of rebate
income already received as a result of previous settlements. This is
done by including a data record for condition type 'S000' (settled
income) in the price determination data.

System Response

Since a different account key does not normally make sense, the system
issues this warning message.
However, a settlement document will be created in any case (settlement
run).

How to fix this error?

Please check whether account determination in its existing form is
desired (settlement schema &V4&).
You may have to cancel any already created settlement documents.
As a rule, no account keys should be maintained for condition type
'S000'. The account keys of the condition type for which settlement is
to be carried out are adopted.
