Receivables accounting

I have a question about oracle Receivables accounting. I'm trying to split the accounting when I apply two invoices to a receipt.

Example:

Invoice 1: 100

Invoice 2: 200

Receipt 3: 300

I need to split the accounting to this:

Invoice 1: 100

Invoice 2: 200

Receipt3: 100

                200

I have the same case with payables but in payables with the SLA and the field Merge Matching lines = No , it works

Regards
