Why can I see package bodies from another schema on the Procs tab?
Package bodies that belong to another schema appear in the Oracle view DBA_OBJECTS but not in ALL_OBJECTS. If you don’t have access to DBA_OBJECTS, then Oracle will not give us that information. If you have access to DBA_OBJECTS but you are still not seeing the package bodies for another schema, go to View→Options→Startup and check “Check for access to DBA views”. Then make a new connection.
