I have posted some Invoices and also cleared them, with a W/Tax type with W/Tax rate >0%. Later, I realized that the vendor is subjected to only 0% tax rate, and I believe we can use RFWT0020 to recreate WHTax data if the vendor is subjected to a 0% W/Tax rate. When I run the RFWT0020, I was able to see the changed WHTax data for the doc.s that I have posted and cleared (when I select the Changes to WHTax code). But, when I run the W/Tax report S_P00_07000134 it still shows the W/Tax rate of X% that I have posted the doc. and not with 0% W/Tax rate. I have deselected the Only recreate documents without W/Tax data also. Its still not working. Please let me know if there is a solution for this.
My second question is - Is there any program in SAP that calculates W/Tax with a rate >0% for already paid invoices.
Any help would be appreciated.
