Cost on SI

HI,

There is process in one of client where they use Inter-company process.

I.E Material is Shipped from Manufacturing company(Company A) to customer but Distribution company(Company B ) raises invoice to customer.

This is standard.

But the trouble is SK Price should be 70% of SI Price.

What I know is SI Cost is SK Price & OK Cost.

Is there any way this can be done via standard?

Thank you for any help.

Regards,

Mayank Pande
