Issue Jet Setup Error - Company Table Permission
Note: Excerpt from Jet Reports Support Site.

When the user selects Jet, Wizard - they get the error that

"You do not have permission to read the Company table"

When they select OK, the Wizard opens but shows none of the Navision Tables. The user has Read permission to the company table as part of the ALL group. We are able to view the jet license in the Jet Options.

The most likely problem is that the All Role is assigned to a specific company. You must remove the company from the role assignment (leave it blank) thereby giving the user access to All in all Companies.

Removing the Company from the Roles for each User resolved the problem. The error does not occur for every user where companies are set for the Roles assigned to the user.
