getting "insufficient privileges" when creating a Quick Report against the table gen_led_voucher_tab

The IFS Model is as such that tables are not accessible to users, typically, only to the Schema owner (IFSAPP) and possibly some DB Read Only such as IFSINFO.

This is a because row level security is typically handled through WHERE conditions on views, and as such, the typical user is only granted SELECT from Views and not their underlying tables. As such, all Entities get their tables projected to a Base View.

Why can you not simply run  select * FROM gen_led_voucher, which is the Base view for the GenLedVoucher Entity?
