How To Fix FWTM393 - Table &1: Rules for account determination inconsistent (==> long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: FWTM - Messages: Withholding Tax Changeover

• Message number: 393

• Message text: Table &1: Rules for account determination inconsistent (==> long text)

What causes this issue?

The conversion tried to create the rules to be used for the account
determination for extended withholding tax from the rules that were
used for classic withholding tax. The system determined however, that
rules have already been defined in the system for the account
determination for extended withholding tax and that these rules do not
agree with the rules for classic withholding tax.
The rules do not agree if the account determination for classic
withholding tax is dependent on the withholding tax code and the
account determination for extended withholding tax is not dependent on
the withholding tax type AND withholding tax codes.

System Response

The Customizing conversion is terminated.

How to fix this error?

Check whether the rules already defined in Customizing for the account
determination for extended withholding tax have been correctly defined.
(Path in SAP Reference IMG: Financial Accounting --> Financial
Accounting Global Settings --> Withholding Tax --> Extended Withholding
Tax --> Postings --> Define Accounts for Withholding Tax --> Define
Accounts for Withholding Tax To Be Paid Over).
If the account determination for classic withholding tax is dependent
on the withholding tax code, make sure that the account determination
for extended withholding tax is dependent on the withholding tax type
and code. If necessary, change the rules and the accounts defined.
Reset the Customizing conversion (if you have carried this out in
update mode), and start it again.
