How to grant Read only access (to all data ) in Navision

Hi,

Our company rely on Navision Consultant from another company for Navision support. Therefore, they need to access our system to help out in troubleshooting from time to time.

However, is there any way we can restrict their access to read only? (e.g. can read all data from all the modules, but cannot perform transaction - no write access.).

I saw there is a Super(Data) role in the system, can I just assign the Super(data)access to the vendor to suit our requirement?

We are on Navision 4.0.

Thanks.
