Hello. Is it possible to have a intercompany invoice for a non stockable item ?

We have different business units with dropshipments. Everything is ok for the items stockable, the invoices intercompany takes the standard cost more an overhead. But for an item non stockable but sell, there is no invoice made. Is it possible to paramater a price for this to generate an invoice ? If not any idea to solve that case.

We need to ship the item and invoice it.

Thank you for your answers
