Issue an invoice for an inventory org within the same OU

Hi ,

We have a scenario where 2 inventory organizations within the same OU showing a relationship of supplier and customer.

Inventory org 'A' supplies printers to Inventory org 'B' at cost. Then Inventory org 'B' sells the printer to an outside party.

Both Inventory org 'A' and 'B' belongs to the same OU.

Inventory org 'A' needs to generate an invoice for the inventory org 'B'.

We are planning to handle the scenario using internal sales orders.

But how can we generate an invoice for inventory org 'B' as both org's are belongs tosame OU?

Please comment.
