EWT adjustment advance payment

Hello All,

The Scenario is like this. Advance payment made Rs.10000/- through special GL TDS deducted is say Rs.225/-on advance Rs.10000/-. Invoice Recd Rs.20000/-. So how should I enter this invoice as I have to adjust TDS already deducted Rs.225/- on advance. If I use T Code F-43 it deducts the TDS on Full Invoice value on Rs.20000/- TDS say Rs.450, whereas I want that TDS should be deducted considering Advance TDS (450-225) Rs.225 only.

appriciated quick response.

thanks,

aruna.
