Unable to switch Invoice Group on the Misc1 tab of Edit Vehicle Data - the option is grayed out.

When the "Invoicing Use Group" drop-down box on the Misc1 tab of Edit Vehicle Data is grayed out, blocking the rep from changing the Invoice Group for a vehicle, have them try the following: 1. From the main ASW screen, select 'Accounting' then 'Billing Setup' - they will be prompted for an override code. 2. Provide the override code from DSPlus (Tech Support -> License -> Override Code). A 'Billing Setup' page will pop up. 3. Select the 'General' tab. There is a check-box labeled "Allow to Change Billing for Each Car" - check the box then save. 4. Go back into Edit Vehicle Data and see if "Invoicing Use Group" is now available.
