PM Cross Plant Authorization Objects

Dear Experts,

My client having two Maintenance Plants XXXX & YYYY ( Logistic Plant = Maintenance Plant = Planning Plant)

I need to restrict cross plant Transaction data  & Master data Creation & Editing while allowing cross plant Transaction data  & Master data Display.

This is my Requirement

• Plant XXXX  users should not be able to Edit Plant YYYY Maintenance Orders / Notifications / Equipment /Functional Locations and vice versa.
• Plant XXXX  users should be able to Display Plant YYYY Maintenance Orders / Notifications / Equipment /Functional Locations and vice versa.
• Both Plant XXXX & YYYY users should be able to Display Both plants MM Transaction data  & Master data ( eg: MM60 , MB52 )

How can I handle this with standard SAP Authorization objects?

Please advice.

Thanks in Advance
