Use the Close orders process to check whether sales offers or orders, or production files or orders have reached administrative completion and can therefore be closed. You could use the process to determine the appropriate time to transfer work in progress.
When you run the process, the relevant files will not actually be closed. The analysis does not result in any changes to the data checked. The analysis merely checks whether all items have been confirmed as complete, to allow the order to be closed if desired. If not all items have been confirmed as complete, you can take action for each item, in order to allow the order to be closed.
