I have execute rights on a stored procedure for another schema. Whenever I run the procedure nothing happens and I get no error, but if I run it as the schema owner, it works successfully. In PL/SQL Developer v12, as the schema owner, I am able to test and step through the code in debug mode, but I am not able to step into the code as the executing user. Is it possible to test and step through a procedure owned by another user, where you only have execute permissions?
