Hi Experts,
A document number in fb03 has withholding tax amounts as zero in FB03. Only the withholding tax type is populated when I checked the 'Withholding tax data' button in fb03, with all the withholding amounts as zeros.

Its clearing document has two line items. For one of the line item when we click on 'Withholding Tax Data' I get a message 'Withholding tax information missing from line item'. For the second line item, it shows all withholding amounts as zeros with only the Wtax code and WTax Type populated.
What does this mean?. Is the withholding amount is automatically generated as zero in this case?
Please clarify.
Thank you
