Intercompany billing with non-stock materials???

Hello,

I've got a question regarding the intercompany billing process.

We've got a sales organisation A which creates orders with items in plant B. Plant B is belonging to company code C.

So in normal case the system will automatically create an intercompany invoice (C is invoicing to A) - but this works only for stock materials.

But, how is the situation with non-stock materials (like licences, warantees)? Is there a way to start an intercompany billing, although the materials are not stock-relevant?

Thanks.
