Restricting TDS based on validation rules for vendor invoice posting

Question

I have two Tax Types assigned in the vendor master. If at the time of invoicing user do not delete the unwanted tax types, system posts both the amounts related to both the tax types.
User has to necessarily delete one tax type which is not required and then proceed with simulating the vendor invoice.
Can this be controlled thru validation rules ? Even if the user forgets to delete the unwanted tax type while passing vendor invoice, validation rule must throw an error asking to delete the unwanted tax types before simulating the vendor invoice.
Please help how to build such validation rule with detailed procedure.
Thanks

Hi Ravi,
I hope you have selected both withholding tax type and code at the vendor master level itself.
It is generally advisable to select withholding tax type at vendor master level and leave the field withholding tax code to be in display mode. Hence during vendor master creation, they can only select withholding tax type and not the withholding tax code. Ensure liable to tax should be ticked against all withholding tax types.
During invoice entry creation either in FB60 or in MIRO, they can select the withholding tax code next to the withholding tax type and simulate and post.
In your case, you cannot delete the withholding tax types at invoice entry level. Ensure to delete the unwanted withholding tax type from your vendor master itself, I mean delete only the withholding tax codes pertaining to that unwanted withholding tax type.
Hope this helps. Assign points if useful
