How to issue material to consumption of external services projects?

We have projects with both material consumption and services. What is the correct procedure to issue this material to the project? How should I do it to make the material appear in Total Consumed Material Cost in Project View?

If I do it using Material Request – Material Issue, it will appear there, but when I then do Delivery from Sales Order, all the material is issued from the warehouse once again with delivery. If I don’t do Delivery from Sales Order, Sales Order stays at the To Deliver state and I don’t have Delivery Note.

If I omit Material Request and move material for project to some intermediate warehouse, to have at least any info, what are real stock levels (ie work in progress warehouse), and after finishing the project I do Delivery from Sales Order, there is no material cost displayed in Total Consumed Material Cost field and I don’t know projects financial result.
