Maintenance work planned by one plant executed by another Plant

Hi SAP Gurus ,

We have a scenario were our client owns Fleet of buses across various states in a country and each state has its own buses and bus workshops.

So every state has its own planning plant and maintenance plant .

·         State ‘A” =Planning plant =1000 and Maintenance Plant=1000

·         State B = Planning plant =2000 and Maintenance Plant=2000

The Maintenance Plans are created and scheduled at each state level.

As these Buses are mobile , if PM02 maintenance order date is due for Bus of state A and the Bus belonging to state “A” has now travelled to state “B” .

Then state “B” workshop picks up this bus and executes the planned maintenance work on it.

State B , uses the all the materials required for Planned maintenance from its own plant stores (Plant 2000)

Now since the  Equipment , Plan , Task list , Maintenance order, reservations  are  generated on Plant 1000 but are executed by maintenance team / material from Plant 2000.

How can I map this process in SAP , so that Maintenance work planned by one depot is executed by another depot?

Thanks
