Show Schema Map on Tables and Columns not working for non-admins

Issue

Show Schema Map is displaying blank page for users other than admin

Resolution

This is expected behavior as OOB The Schema Map functionality is allowed to users with personalize_dictionary role. You can customize it by using one of these solutions:
  1. Grant the personalize_dictionary role to the user.
    Please note that if you add this role to user, the user will have high-level privileges over the instance, and access to the Application "System Definition", it is not a role that you will want to easily assign to a user.
  2. Another solution can be to customize the script include named 'ERDProcessor' (at line 495).
    https://<instance-name>.service-now.com/sys_script_include.do?sys_id=5de8f42137130000dadaa3549dbe5daa
    You can make it work by updating line 495
    • FROM:
      • if (!gs.hasRole('personalize_dictionary')) {
    • TO:
      • if (!gs.hasRole('personalize_dictionary') && !gs.hasRole('<role you want>'))
