Use this tab to view the history of order structure changes for the interim demand header. The system will create a history record when changes in work scope definition occur. You can see history records caused by maintenance level changes, repair orders disconnections and manual cancellations of interim orders.
Changes in work scope definition can result in additional parts being exposed for maintenance, or previously-exposed parts no longer being exposed. These type of changes require updates to the interim order structure where possible. When more parts are exposed, it is fairly simply to update the structure with additional interim orders. However when previously-exposed parts are no longer exposed, deleting the associated interim orders from the structure is more complex. If the interim order is still in a Created state, the order will be removed from the order structure. If the interim order is in any other state, the order will not be removed from the structure.
Disposition orders also may sometimes change to disassembly orders as a result of a work scope change, if the state of the disposition order allows this. Thus, a part previously intended to be dispositioned is now scheduled to be further disassembled, since the work scope change resulted in requiring some or all of the components of this part to be further exposed. Such changes are also recorded in the History tab.
