Diagnosis
During legacy data transfer, a value was transferred as an "accruedvalue" for accrual type &V1&.
As a result, the Accrual Engine tries to post this value as aperiodic posting.

System Response
However, the corresponding accrual type &V1& is not meant for periodicpostings.

Procedure
Change the Customizing settingsfor the Accrual Engine (View V_TACE_ACRTYPE).
