Link between Billing Invoice with credit memo in SAP table

Dear Friends,

I have one query regarding this below.

I have 3 billing invoices and after that i have generate one credit memo request with ref. of 3 invoice.

Now i am creating credit memo with ref. only with 3rd or any one invoice.

Now in VBFA i can not relate credit memo with billing invoice exactly because it displays 3 billing invoice against credit memo but i need only one billing invoice.

In VF03, we can see exact relation in display document flow but in table i can't relate.

Please suggest table relation.

Regards,

Shivam
