Balance INVOICE matched to CREDIT MEMO

Hi all,

I would to know if there is some function in Oracle EBS 11.5.10.2 that allow to see the balance to pay of the invoice.

For examaple:

1) Insert Invoice XXXX for 725 EUR

2 ) Insert Credit Memo YYYY for -25 EUR

3) Match Credit Memo YYYY to Invoice XXXX.

On the standard form of the Invoice I can't see that the correct balance to pay is 700, also when the user try pay the Invoice XXXX by payment batch system return 725 EUR

Could someone help me? 

Thanks

Dario
