The business type is option is specific to certain retailers (Home Depot mostly) and suppliers where the supplier provides an item which is generic and could have many competitors supplying the same item regionally across the country. A good example is a lumber fir 2X4X8 stick. If you receive data from the retailer, its possible you receive data for your sales as well as other suppliers due to a situation known a "shared SKU". In this instance, you can elect to have Avantalytics segregate your business from your competitors regionally. If this is the case, the value of "Active/Primary Business" will represent just your business, while "All Sales" will widen the net to return sales on the item regardless of the supplier.
