REATAINING A PORTION OF AMOUNT WHILE MAKING PAYMEN (RETAINAGE)

 We are in 11.5.10.2.  We generate Jobwork Invoices through Payable Open Interface Import . These invoices attract TDS ( India Local). Now we want to retain a small portion this jobwork amount as a 'Deposit' an dpay the balance to the Vendor.We want to do this with following condition.

1. Balance amount should not be kept in Vendor A/c.

2. Amount should automatically get credited into a GL A/c. ( separate code for each vendor)

Can any one  help me?

Thanks
