authorization in sap APO

Dear SAP,

My expectation is: We have 15 Locations in our model. I want to create 3 administrators for each 5 Locations. Each admin of each group of Locaotions(5 Locations) can only create Role for users who belongs to 5 Locations that he is responsible for.

For instant:

User Location

1. HUNGTH (Administrator) 0110

2. DUYENNX Belongs to 0110

3.GIANGLT 0110

4.HOANGPT 0210

- Role of HUNGTH can only create and maintain Roles for DUYENNX and GIANGLT.

Please help us to create role for HUNGTH.

thanks so much
