Hi Van,
The error may be caused by the CO-PA customizing. If the costing key is currently set up so actual cost component split is taken over from ML. It is at plant level from the line item that is used to determine the cost estimate.
If you have assigned this costing key to several material types for those material types, an actual cost component split will be read, independently if ML is active in the plant or not. This leads to the error.
You should delete all assignments of costing keys to material types or use the customizing function 'assign costing key to any characteristics' instead.
There, you can assign the material types again, and set up an additional condition that ML is active in the plant.
You can find these details in the customizing as follows:
SPRO -> IMG -> Controlling -> Profitability Analysis -> Master Data -> Valuation -> Set up Valution Using Material Cost estimates:
- Define Access to Actual Costing/Material Ledger
- Assign Costing Keys to Material Types
Best regards, Gordon
