From the MRO Interim Order Structure page, you can use the commands Release Disassembly Orders, Release Disposition Orders, or Release Assembly Orders to release the appropriate type of interim orders, i.e. either disassembly, disposition, repair, or assembly interim orders.
The interim orders being released must be in a Created state. In addition, the parents of these interim orders in the order structure should be in state Released.
This will create MRO shop orders of the appropriate type, i.e. either disassembly, disposition, repair, or assembly MRO shop orders.
