Cross-comp.code/acct accumulation: Paying/sending co.code must be unique

What causes this issue?

The extended withholding tax function is active for the company code
specified, and there are withholding tax types for which cross-company
code or cross-account accumulation is active.
In this case, paying and sending company codes must correspond for all
company codes linked by cross company code/account accumulation (i.e.
belonging to the same tax on sales/purchase group). This restriction is
necessary in order to ensure that withholding tax is processed
consistently in this special case.

How to fix this error?

Check your Customizing settings for the automatic payment program
(table T042).
