SAP Error Message - Details

• Message type: E = Error

• Message class: 7Q - Messages for new withholding tax functions

• Message number: 020

• Message text: Postprocess open items after changing relevant withholding tax types

What causes this issue?

As a result of changes you have made, you may have changed the quantity
of relevant withholding tax types.
A withholding tax type is relevant if the following conditions apply:
The withholding tax type is entered in the master record of the
business partner and indicated as subject to withholding tax (vendor)
or authorized to deduct withholding tax (customer).
The company code is defined as authorized to deduct withholding tax for
vendors or subject to withholding tax for customers for this
withholding tax type.
The posting date is in the validity period for the authorization
deduction (customer master record or withholding tax data for company
code).

System Response

If the quantity of relevant withholding tax types changes, open items
posted before the change cannot be activated and therefore not cleared
(inconsistencies between withholding tax information in the open items
and information in the company code or master data).
In the document display, the system displays relevant comments about
the validity of the withholding tax information in the withholding tax
dialog box; <ZK>New withholding tax type</> if a relevant withholding
tax type was added after document entry, and <ZK>Withholding tax type
no longer relevant</> if there are less relevant withholding tax types
after the document entry.

How to fix this error?

After you have changed the relevant withholding tax types, you have to
adjust the open items for the current relevant withholding tax types.
For new withholding tax types, new withholding tax information has to
be generated and for withholding tax types that are no longer relevant,
the withholding tax code must be deleted in the existing withholding
tax information.
You can use report RFWT0010 to adjust the withholding tax information
to the relevant withholding tax types.
Start report RFWT0010 after changing the relevant withholding tax
types.
