Diagnosis
The assignment of one object to another is not appropriate from anaccounting perspective, or is technically not possible.

Example
Assigning an asset as an account assignment object for a correctionposting is not correct. The system assigns costs from non-deductibleinput tax or revenue from deductible input tax that were posted duringinput tax correction. If account assignment were made to an asset, thiswould lead to the costs/revenues being capitalized, which is not allowedduring input tax correction. Instead choose a (higher level) real estateobject or a cost center as an account assignment.
