How To Fix M8420 - Bestellpreismenge führt zu fehlerhafter Bestellentwicklung

SAP Error Message - Details

• Message type: E = Error

• Message class: M8 - Invoice Verification/Valuation

• Message number: 420

• Message text: Bestellpreismenge führt zu fehlerhafter Bestellentwicklung

Was verursacht dieses Problem?

The invoice references a PO item in which the PO unit of measure
differs from the PO price unit of measure. When the invoice is posted,
the following inconsistency arises in the PO history:
The difference between the total quantity invoiced and the total
quantity delivered had a different sign in the PO unit of measure and
in the PO price UoM. This means that there was a delivery surplus in
the unit of measure, and an invoice surplus in the other. This way we
can avoid having to enter further goods receipts that will not be
valuated.

Systemantwort

The system does not allow you to post the invoice.

The PO price quantity must be at least &V2& &V3&.

The PO price quantity must be at most &V2& &V3&.

Wie behebe ich diesen Fehler?

Check the quantity and the PO price quantity and make changes where
necessary.
If your entries are correct, then you need to analyze the PO history.
If there are already inconsistencies in the PO history, then you will
have to cancel any goods receipts and invoices containing the
incorrectly entered PO price quantity and then re-enter them. If this
is not possible, then you can correct the PO history by posting an
invoice with a PO price quantity

of at least &V2& &V3&

of at most &V2& &V3&

and then performing a cancellation.
