In previous AX version, we can use security keys to manage user's permission by user group.

AX2012, user group hasn't used. And security keys just keep for compatiblity with old version.

You can create security keys in AOT directly and object's security key property is disabled through you can create a security key in a project.

That is meaning security key is not allowed to use.

And i tried to create a security key to control some codes and it doesn't take effect.

Then AX2012 import a new method to do codes permission management. I followed Microsoft document as below but failed testing.

And another document to write code access  security in AX2012 but failed too.
