Lookup Lists are very flexible and powerful options to customize your feeds.  They can perform several functions including:

• Allowing you to get additional data
• Replacing existing data
• Building a list of products to exclude from feeds

You may create as many lookup lists as you need.  Lookup lists can be created individually or uploaded in bulk.  

Prerequisites

You should be familiar with the following topics before continuing:

• Learn about using ChannelAdvisor as your inventory management system
• Customizing Templates

Most applications of lookup lists require that they be paired with a business rule.  This is because the lookup list needs the expression portion of a business rule to perform an action.  Some lookup lists (that are not exclusion lists) can be mapped directly within a template in order to substitute an inventory field based on a lookup list.  

The Lookup List View

You can view the following in the Lookup List view:

• Name - The name of the lookup list
• Description - The description of the list created.
• # Items - Indicates the number of entries or mappings in this list.
• Date Created - The date the list was created.
• Updated By - The username of the person who updated the list.
• Date Updated - The date for the last update to the list.  
• Actions - Allows you to Copy or Delete user-created lists.  Delete is not an option for system created (default) lists.
