For instance, after I ring in a sandwich, I want to go to the drinks screen... but the drink should not be a modifier to the sandwich.
To to go next screen automatically after ringing an item, do the following:
1. Go to Management Console - Merchandise - Modify Merchandise
2. Find the Item you want to edit and click Edit
3. Click on the "Links" tab
4. On the drop down menu for the first available link, select the screen group you want to go after you have rang in the item
5. Do not select any checkboxes
6. Click OK to save your settings
