Is this W/O for airframe maintenance or internal component repair?
Production W/Os address airframe maintenance or components installed on an airframe. They can be created from multiple windows, but Production/ Update/ W/O contains all possible options.
Shop W/Os are used to handle the internal servicing of parts, including repairs, overhauls, etc. These are created from the Shop module. If the Work Order being created is for specialized component repairs or overhauls, then refer to the Shop Work Order Process Flow.
