This week's Xact Hacks video covers the BIG difference between Copy/Paste and the Retrieve Scope option in Xactimate. Don't lose items in translation from room to room - Retrieve Scope every time to ensure everything is captured.
WRITTEN EXPLANATION: Right click in the room you are trying to transfer line items to. You can right click in the white space or on a blank line item. Select Other Options and then Retrieve Scope. This will completely copy the scope from Room A and transfer it Room B (where you right clicked and were trying to transfer to). Purple line items (graphically sketched) will not copy and paste!!! Retrieve scope does transfer them over.
