Shopping Lists 
You can use this function as a:
Template for orders that are made regularly
Search criterion
Your User Interface (UI) Configuration Manager has given you shopping list authorization.
A shopping list must have at least one item in it to serve as a search criterion.
To display all items in a shopping list, the search criterion must be reset before the shopping list is selected.
This is because the search UI treats the shopping list as a search criterion. Consequently, any other active search criterion reduces the items displayed to a subset of all the items in the shopping list.
To display all shopping lists, including empty ones, on the Shopping List page, one of the following conditions must be met:
No other search criterion has been entered
The search has been reset
When a shopping list is selected as a search criterion, the system restricts the search by removing any items not included in the list from the search result.
Items can be added or removed from shopping lists in the shopping cart preview.
Note
Depending on authorization, users can modify either their own shopping lists or those of others.
