hiWitholding tax options for a supplier with different witholding tax rates

Hi Team,

Need to clarify on a point. To my understanding, we need to default the witholding tax code @ supplier site to calculate withholding tax. Assume my supplier has two or three WH tax codes as different rates will be applied on the basis of nature of transaction. How can this be managed. While validating invoice or before making payment, the user should get to see the LOV of WH tax applicable for the respective supplier and choose the WH tax code based on the nature of the transaction. Please advice..
