If you have customized the Group Names (i.e. ‘Common’, ‘Sales’, ‘Service’, ‘Marketing’, ‘processes’) located in the form navigation pane of Microsoft Dynamics CRM, you need to assign the appropriate permissions to users so they can actually see these changes. The privilege inside of the security role that needs to be turned on is called ‘ISV Extensions’ on the Customization tab. This privilege is already given by default to management roles. If a user does not have this privilege they will not be able to see any changes to the headers– rather it will look like no change has been made at all.
