Hello Aamod,
what the user sees on the New Dataset dialog under Available Views depends on what they have access to under _SYS_BIC in the HANA System. If the user has SELECT on _SYS_BIC they will see all models listed under Available Views.
To limit what the user sees under Available Views their SELECT privileges need to be limited to the specific views you want them to see.
For example if you want user LUMIRA to see only analytic view MYPACKAGE/AN_MYVIEW you grant them SELECT privileges to "_SYS_BIC"."MYPACKAGE/AN_MYVIEW" which can be done via HANA Studio security UI or directly with SQL statement:
GRANT SELECT ON "_SYS_BIC"."MYPACKAGE/AN_MYVIEW" TO LUMIRA;
Thank you
