AR/AP Netting and Intercompany AR Negative Invoice vs Credit Memo

Content

We are using the Intercompany module to process AR/AP. AR transactions from the Intercompany module are creating negative invoices instead of credit memos. 

We also have netting agreements setup between the intercompany relationships to net any amounts possible (within the currency).

We have a situation where the balance on the AP side is a credit amount that is the proposed netting amount against several AR transactions. It just so happens that one of the AR transactions is a negative invoice. 

When we run the settlement for this batch, the settlement errors because it cannot create a negative receipt against the negative invoice that was picked up in the settlement batch.
