How to get access to isv module in nav 4.0 sp3

Hello , I have to make customization in one module called "Job Order Production’, but do not get access to it. I have developer license,also we are Microsoft partner. But we can not get access to any table or form of that module.

So please help me how can I solve my problem.

Thank you.

Hello

If the add-on developed by some other partners and if they have used protected object range then you can not access that with your partner license .

Contact either MS or partner who developed the add on
