I faced with the problem at Toad 11.6.1 I cannot open package body of Oracle database on Toad 11.6. So when I click button Toggle Spec/Body The following info was showing:
Cannot navigate to package body because this spec has no body
But when I connect to the same DB with with the same username with TOAD 10.1.1 everything is ok. It means that I have access to see the package and it's body. I have no idea what maybe the problem.
