The attribute cannot be directly added to the selected type because it belongs to a Sealed Management Pack.

In order to add the attribute successfully, we have created an extended version of the type which will be located in an unsealed Management Pack.

You can use our suggested default extended type name or change it to a name of your choice.

You can also use the default Management Pack as we have suggested, choose another one from the dropdown menu or create a new one.
