In order to utilize the Export to Excel feature, all users must have proper permissions configured or they will get the following error: "You do not have permission to export grid data".
Permissions can be configured through the Centerbase admin tool by the company's designated administrator. The download for that tool is located here:
This permission is located under 'Manage Users'. Click the desired user and then select the 'Additional Permissions' tab and check the 'Export Data' permission. This will need to be enabled for every user that needs the export feature.
