Before you conclude the work order, you have to report in all work order data, and get all postings authorized. Your work on the work order must also be completed and the actual completion date must be given.
When you have entered all the necessary information and have completed the work, change the status to 'Finished' to conclude a work order. As the result, a work order becomes historical and could be used for information purposes only. The information on a historical work order can only be changed, or reused when you are using the Reopen right mouse button option. The reopen feature has the following aim; if you for example have forgotten to register transactions such as time, material, or external costs, it is always possible to add this on to a historical work order.
