How to automate processing of orders (type - SERVICE ORDER) and its lines (BILL ONLY)

Hi Team,

We are generating service orders from Service Requests (SR) by submitting charge lines in Service Requests. Order type for this type of orders is XX….SERVICE ORDER and lines are of '….BILL ONLY' line. Orders and their lines are correctly generating as per type defined.
My question - How to automate processing of these orders (type - SERVICE ORDER) and its lines (BILL ONLY), so that data (amount, date…) will go to table ra_interface_lines_all without doing pick release/ship confirm of this. There is no material involved in these lines and associated items are of type 'labor/expense' only.
