R-CSP hook is called when the system needs to retrieve a sell price. Unless you're assigning or changing stock items on a transaction, I can't immediately think of why it would be called. It wasn't designed to let you decide that it should be called from an invoice raised from one area and not another.
Is there some particular situation where you are finding it is being called even though quantity or sell prices are not being changed on an invoice?
