Can't Alter the Customer Group

Why can’t I alter the Customer Group for any of my Customers?  It is greyed out.

Solution

Access to change a Customer Groups is controlled by the setting for a staff member

• Allow Access to Terms and Pricing

This is because a Staff member who is not able to change the price level or default discount for a Customer, should not be able to adjust the Customer’s group setting, as that may result in the Customer having a discount set through the Discount Matrix functionality.
