TDS : payment Tax code issue

Hello Experts,

we assign both the Invoice Tax Code & Payment Tax code of TDS to a Vendor. now when we are posting invoice we are removing the TDS Tax Codes of Payment.

it may happen that a end user may forget to remove the payment code, this is quite natural & then there's a lot discrepancy during posting full payment for the same invoice.

what do i do to solve this, i do not want the payment codes to appear when posting invoice, is this possible, please help. thank you.
