Question on Depot Repair Charges to Order Management

Hello,

I have question on limiting lines being picked from depot repair to order management for invoicing. 

How is it possible to only select an expense line type to be sent to order management for invoicing to happen?

right now i have RMA order, repair estimate data = material, labor, expense.  Then from WIP Job I import estimates to actual tab, will get same material, labor, & expense lines.

now i want to only get the expense line to be sent order management for invoicing to happen.  How is this possible?

Thank you
