Codeunit Error

Hi -

I have a very simple codeunit 50010 in which I am just inserting a record into table 5071 Campaign. When I run this code I get an error
'You do not have the following permission on Codeunit Insert Campaign::Execute'

Now, In the

User table --->Permission Set-->I have Super assigned and the company field is left blank.
In Codeunit 50010 I went to permission and have given indirect permission of Read, modify, Insert and Delete.
In SQL I have DBowner, Sysadmin and all SUPER permission as per other forums description about this exact error message.

My question is can't I create any codeunit with a Partners Developers license and has something changed in NAV 2016 with regard to codeunit creation using Partners Developers license.

Any help is highly appreciated.

Thanks
RS.
