I am trying to view procedures in the Schema Browser of Toad 10.6.1 but when I clicked on the 'Procedure' tab I got:
"ORA-00942: Table or view does not exist"
Toad 10.6.1 uses the following SYS tables to find the information for the 'Procedure' tab.
sys.obj$
sys.USER$
sys.idl_char$
sys.procedureinfo$
Run the following queries one at a time to find out which tables you need rights to.
For issues like this, you can check which backend tables Toad need by running a SQL Monitor session.
