NAV License File and Associated Granuals

Does somebody have some recommended reading on the explanation of a NAV license file and what objects you can and can’t change.

I need to prepare a report for management, detailing the things we can do internally (we have an internal development team with CAL experience) and those things that need to go to our NAV partners.

We just have a standard end user license, but I notice in the object designer there are some things I can edit and some CAL I can access, I assume because we have the following design based granules

7110 Report and Dataport Designer

7120 Form and Page Designer

7130 Table Designer

7140 XML Port Designer

I think a developer license opens up more access with additional design granules, but it’s more about the access we currently have.

Any help / recommendations ?
