Configuration and setups related to intercompany repair

Summary:

We have scenario where there are 3 different LE and BU, Example NZ BU , AUS BU , US BU.
NZ BU - Created RMA sales order (Order management Setups Completed)
AUS BU - Receives the defective item and ship to US BU. (Intercompany transfer order Completed)
US BU - Create Mainteance Work order (repair the Product ) and ship it back to AUS BU. (MWO NOT completed )

We have completed the intercompany configuration where Item will be shipped from AUS BU to US BU.
What configuration is requied so that once US BU receive the defective item through transfer order and create MWO?
