Validation for With holding Tax codes
I am doing a validation for withholding tax codes. When ever an invoice or payment is posted to a vendor, the business place and section code has to be mandatory.
This validation is working ok, but my concern is that even for vendors for whom tax codes are not assigned, this is a mandatory field. Thus can we do any validation where in business field and section codes are to be mandatory only for those vendors for whom withholding tax codes are assigned?
Thanks & Regards,
