We need to process a cube in SSAS.
The datasource used to generate the cube is an SQL Server standard tabular database.
The user which connects to the database has a sys_admin role with all permissions, but we need to downgrade these permissions for security reasons.
The question is which roles/permissions are needed for the sql user in order to connect to datasource to process the cube (without reaching sys_admin level) ?
Tried db_owner role, without success.
