M7021 consumption batch MB1A

Dear,

I want to consume a quantity on a process order via MB1A. Via interfacing the reception of the purchase order has been done a wrong batch and also wrong valuation type (since material ledger is active on batch level).

From accounting point of view everything is okay, however when I'm trying to consume the raw material. I got the error message M7021.

The MARD table contains the correct quantity

The MCHB table contains the correct quantity

This is also visible in the transaction MB52, MMBE. So I wonder why the system doesn't allow me to consume the raw material.

Somebody an idea, which table could also contain relevant data
