Very urgent subcontracting and intercompany

Hi

I have a big problem.

I create a customer order to company A from an external customer.

When I release it, it creates a purchase order with a part which is a purchased part (with components to send to the supplier). The supplier in an internal supplier in another company B.

I can’t ship the components to the supplier

The only function I have in the purchase order is “Purchase order line compents”

Please could you help me ?

I have a question :

Is it possible to do full subcontracting with postdeduction of components in the intercompany flow ?

Thanks for your ansmers
