Abap Report Authorization Checks

Hi. I have some question on customized abap report to be based on user role organizational level.

May I know how to program the abap report such that the report will show only data based on user role organizational level (Plant, Company, SalesOrg etc)?

For instance, if userA role organizational level for plant is plantA, the abap report will only show data for plantA. If userB role organizational level for plant is plantB, the abap report will show data for plantB.

May i know how to program the abap report?

Appreciate any guidelines.
