Match partial paid invoice with customer payment

Question

Hi all,
My company FI user told me that those partially paid invoice will still shown full amount in the FBL5N report and also Statement of Account (F.27). Besides that, the customer payment that used to knock off the partially paid invoice also will shown to deduct the already paid amount.
But the user said that both of the FBL5N and F.27 are not link the partially paid invoice and customer payment together or don't have a key field to indicate which payment is refer to which partially paid invoice. When the next time they receive another payment and want to knock off the outstanding invoice amount, they are not sure that which invoice should they knock off.
For example, we have the list of invoice and payment below:
01/02/07 Inv001 $1000
02/02/07 Inv002 $2000
10/02/07 Inv003 $4000
11/02/07 Inv004 $5000
01/03/07 pay001 $1000 - knock off the Inv001
01/04/07 pay002 $3000 - knock off the Inv003 partially
So in FBL5N and F.27, the list is shown as below:
02/02/07 Inv002 $2000
10/02/07 Inv003 $4000 (still shown as full amount instead of outstanding $1000 only)
11/02/07 Inv004 $5000
01/04/07 pay002 $3000-
So when FI user receive another $3000 payment, they should knock off the Inv003 outstanding amount $1000 first then only knock off the Inv002.
But in the FBL5N and F.27, we can't find the relationship or key field to match the old payment (pay002) to the invoice that knocked off by it. Due to our invoice list may very long, such as more than 50 invoices per customer, so we need to spent a lot of time to trace back all invoice.
So the FI user requested I to modify the F.27 statement to match the payment and partially paid invoice. But I already search through many tables, such as BSID, BSEG, BSAD, etc and still not able to get the information that requested by the user.
Can anyone tell me that which table, which field should I refer to or any method to get the information?
Thank you.

Hi,
Check field BSID-REBZG. When you create a partial payment this field will have original invoice number.
- Let's say you have invoice INV#1 with amount 100.00.
- You create a Partial payment of amount 45.00 and the payment doc is PAY#1.
- Now if you look at the table BSID, there will be two entry in this table
  1. BELNR = INV#1, WRBTR = 100.00, REBZG = 'Blank'.
  2. BELNR = PAY#1. WRNTR = 45.00, REBZG = INV#1.
This will help you determine the partial payment. I hope this will help you find solution your problem.
