To be able to access SAP HANA views that have been generated from the BW system, you need certain authorizations in the SAP HANA system and in the BW system.
You can use various transactions for administration of authorizations. More information: Administration of the Generation of SAP HANA Views
To be able to access SAP HANA views that have been generated from the BW system, you need the following authorizations:

These include the following characteristics:
More information: Prerequisites for the Management of Analysis Authorizations
The other authorizations that are needed are generated from the BW system when activated and assigned to the user via roles. An object authorization SELECT is created here for a generated view, and SAP HANA analysis authorizations for the BW analysis authorizations. If a SAP HANA view is generated for a query with SAP HANA exit variable, then the user _SYS_REPO contains the object privilege EXECUTE for the SAP HANA exit procedure.
The roles that are generated always have the following structure for InfoProviders (also for InfoObjects as InfoProviders): <RS2HANA> / <SID> _ <Name of the InfoProvider>. Roles have the following structure for InfoObjects with master data: <RS2HANA> / <SID> _ <Name of the InfoProvider>. If both types of views are generated for an InfoObject, the reporting view is given the following name: <RS2HANA> / <SID> _ <Name of the InfoProvider>_REPORTING.
You can define in Customizing that the SAP HANA authorizations are assigned to the user directly instead of via roles. To do this, go to Customizing and choose . You can use assignment type M here to set assignment of multiple roles. The naming convention for the roles then changes to <RS2HANA> / <SID> _ <Name for the roles specified by you in Customizing><user name>.
BW authorizations cannot be converted 1:1 to SAP HANA. The following restrictions apply to using BW authorizations as SAP HANA authorizations and are not supported:
Hierarchies are converted into a flat list, and an additional technical column (which is invisible) is added to the SAP HANA view.
If changes are made to the authorizations in the BW system, the SAP HANA analysis authorizations are not automatically adjusted. You should therefore schedule a regular process chain with process type Replicate Authorizations of BW Users to SAP HANA.
