Hi Andila,
I didnt understand when you mentioned you created a "OLAP View" using a procedure. Did you create a Analytic View or You created a Aggregate Table?
If you have a view and you want to grant access to _SYS_REPO
Goto Security (From authorized user) --> goto _SYS_REPO --> Add the View and grant SELECT access with "Grant Option" as "yes".
