How To Fix FWTM392 - Table &1: Posting key inconsistent (==> long text)

SAP Error Message - Details

• Message type: E = Error

• Message class: FWTM - Messages: Withholding Tax Changeover

• Message number: 392

• Message text: Table &1: Posting key inconsistent (==> long text)

What causes this issue?

The conversion tried to create the posting keys to be used for debit
and credit postings for extended withholding tax from the posting keys
that were used for classic withholding tax. The system determined
however that posting keys have already been created for extended
withholding tax in the system and that these do not agree with the
posting keys for classic withholding tax.

System Response

The system would post documents differently before and after the
changeover. The Customizing conversion is terminated.

How to fix this error?

Check whether the posting keys defined for extended withholding tax in
Customizing have been defined correctly. (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 these posting keys have been defined incorrectly, and
if you have not yet carried out any postings with extended withholding
tax in the current client, you can delete these entries, reset the
Customizing conversion and then start it again.
