Symptom
The "account assignment category" of the purchase requisition created by MRP is "U" (unknown)
Environment
SAP S/4HANA Cloud
Reproducing the Issue
- Run MRP for a Non-Valuated Materials to create purchase requisition.
- The "account assignment category" of the purchase requisition is "U"
Cause
In configuration 'Define Plant Parameters Overview' , the Account Assignment for Non-Valuated Materials is set as "U" by default.
Generally the MRP run is not able to determine valid accounting data for purchase requisition for non-valuated materials.
However, the processing of purchase requisitions require at least an account assignment category to allow the further processing of these documents.
Based on that the MRP usually assigns an account assignment category for an unknown consumption posting to purchase requisitions for non-valuated material.
And therefore, account assignment category 'U' was delivered for this purpose.
In addtion, the MRP does not support the creation of purchase requisitions with alternate account assignment categories like 'K' or 'F' as the MRP is not able to determine and validate the concerned accounting data accordingly.
Resolution
This is standard behavior.
