Withoolding Tax reversal Issue

Dear All,

I am stuck up with withoolding tax scenario

Client wants to manually change the base amount of witholding tax at the time of invoice in order to avoid debit / reversal of TDS at the time of advance adjustment

e.g.

Advance to Vendor of 10,000 (TDS 1000) - F-48

Vendor (Special GL)  Dr.      10000

     To Bank                          9000

     To TDS Payable               1000

Invoice (Base Amount is manually changed) e.g. Invoice of Rs 1,00,000 - FB60

Exp A/c Dr.                1,00,000

     To Vendor              91000

     To TDS Payable     9000 (90,000 X 10%)

Payment to Vendor (After Advance Adjustment) - F-58 / F-53

Vendor                81,000

TDS Payable      1000

     To Bank          82,000

'Central Invoice' is not ticket in withholding tax type since I dont want system to reverse tds for advance adjustment

Please suggest a way so that system does not reverse TDS at the time of payment(f-58) which was originally paid at the time of advance(F-48)

p.s. TDS of payment is not selected at the time of invoice booking

Thanks

Nishu
