Intercompany billing for 3rd party items - release 4.7

Hello,

I have a scenario where I would expect an inter-company bill (Sales org belongs to company code A, plant to company code B), however, since this is a Third Party Scenario (item category TAS), no inter-company billing is possible. I tried billing the order as well as the inbound delivery, but no IV document is being created. I would expect an inter-company bill from company B, who got billed from the Third Party vendor) to company A, who made the sale.

Upon receipt of the 856 IDOC (ASN), the system creates an inbound delivery (type EL), however, LIKP does not have the necessary fields filled for IC billing (VKOIV (selling sales org.) etc.), nor does the delivery item show any billing relevance status.

I have tried numerous things, such as making the delivery item category (ELN) relevant for billing (tried A and D) and maintaining copy control between EL and billing type IV.

Does anybody know, if it is possible to create an inter-company bill in a Third Party scenario (i. e. no outbound delivery, only an inbound delivery gets created upon receipt of the ASN)?

We are in release 4.7.

Thanks!
