As a powerful ERP, SAP Business One offers up to 10 segments to describe your business transactions out of the box; these are the dimensions that you measure your business by. Good examples of these types of dimensions are items like Company, Division, Business Unit, Region, and Account code. Additionally, when you want to do margin (or any other operational) reporting out of the GL, you might also need to capture data such as Product, Customer, Vendor, and Employee.
