Select the store to designate as the master store from the Master Store drop-down list. The ‘Master Store’ setting specifies the store that takes precedence when importing data, meaning Aloha Insight reports and Drilldown Viewer use the item IDs, names, and sales categories from the master store. You can add new category and item data for individual stores, but master store data overrides categories and items specified by other stores if the IDs are the same. If an item does not exist at the master store, but does at another, Aloha Insight still imports the item.
