how to find to which table the net payment is posted....

Hi all

i am making payment to a vendor for 3 different invoices in a single payment run (F-58) with cash discount.Now i could like to know that in which tabe the net amount for the all the 3 invoices were posted .

eg:

Invoice No Amt Cash discount Net Amt

8753 12000 1200 10800

9878 27000 2700 24300

10098 21000 2100 18900

Total 60000 6000 54000

Net Amt payable (F-58) 54000

When i m checking it in FBL1N the system is displaying the total payment amt and in a sperate col. the Discount amt.

I want to know in which table the net amt (i.e. Invoice amt - Dicount) will get updated ,so that i can pull the amt from that table for my development.......

Its urgent
