People, People...Are we missing a point here? Isn't it the job of the Svc Adv. to add lines to ticket? And doesn't he/she know that it has to be done? There is usually a tech in front of them waiting for an approval. Once the Advisor tells the tech to go for it, ADD THE LINE!! Contrary to popular opinion, the Counterperson doesn't wait for the tech to come back to the counter, instead, they go on to the next tech/customer.
Just charging parts to any ole line is dangerous too. Tickets get closed with the wrong parts on CP/Warranty lines, sometimes with no way to go back. Let's look at this scenario...A part gets charged out on a CP line, the line gets zero charged because there is supposed to be a new WRO written. The part doesn't get charged to the new ticket, and (here comes Pandora) what happened to the Warranty Return Part that didn't get signed off because it is NOW Warranty, not CP?
I went back to the old adage (sorry about not being PC) "NO TICKIE, NO LAUNDRY." And guess what? It worked, with minimal wasted time and lost productivity. It forced everyone to do things now, not sometime.
