M8551 - Overview

• Message type: E = Error

• Message class: M8 - Invoice Verification/Valuation

• Message number: 551

• Message text: Invoice document contains too many different tax codes

What causes this issue?

You attempted to enter or process an invoice in which more than &V1& tax
codes are contained in the items. Invoice Verification only supports a
maximum of &V1& tax codes per invoice.

System Response

The system refuses to allow you to enter or process the invoice.

How to fix this error?

Check the original invoice from the supplier.
If the original invoice only contains &V1& tax codes, the system
assigned wrong tax codes to the invoice items. Check the invoice items
in the system and change any wrong tax codes. Also check the purchase
orders to which the invoice refers. A wrong assignment was probably made
in the purchase order(s). If this is the case, change the info records.

If the original invoice contains more than &V1& tax codes, the invoice
cannot be posted in Logistics Invoice Verification. You must post the
invoice in the classical Invoice Verification component.
