Increase in TDS base amount – We are doing a big expansion at a new site. We deduct the amount on account of retention from the vendor bills. for eg: If the bill is of 1 cr. and the retention deducted is Rs. 10 lac, we make payment of Rs. 90 lacs to the vendor but deduct TDS on Rs. 1 cr.

One issue is that user has to enter the base amount & TDS amount manually. The other issue is that the system behaves abruptly when the invoice is settled against such advances.
