Assigning is necessary so that item groups that are not sold at that location do not appear there. If a shared menu is set on a location without that item group assigned, it will not appear on that location's menu.
To assign the item group, open a previously created item group, and select the "Assigned locations" heading. If you have just created the item, the "Assigned Locations" heading will appear just after the item group is created 
To assign the item group to a location, select "Edit Assigned Locations" this will show a list of all locations in the company. There is the option to individually assign locations, or to assign to all locations at once.
Once the item group is assigned to a location and the changes are saved, the location will appear in the assigned locations list.
Once the item is assigned to the correct locations, you can now adjust the location-specific information. This is information that can quite often vary between specific locations.
