In a multi-store environment, one location is designated as headquarters, and this location should be the place where most inventory is received and then allocated to other stores.  Usually this location would be store 1.  When you add items in a multi-store configuration, the Allocation screen will prompt you to distribute them to stores.  Inventory can also be added at any other store location, and a modified numbering system will be applied automatically.

The primary inventory location will have a numbering system that contains a category ID followed by a five-digit item ID number.  For example, it might be 100-00001.  When items are entered at any other location, The Edge will automatically expand the item number to include the store and an extra digit before the five-digit number, e.g., 100-2000001.  This way, no one item number is used twice.  For more about allocating items to other stores, see the section in the User Guide entitled Allocate Inventory.

If it is common practice for you to add product at another store, be sure to test the item barcode to ensure that it scans properly with the expanded numbering system.  Your tag layout may require adjustment to fit the expanded numbering.
