At XYZ company, a sales rep can be assigned to more than one customer. The sales rep can be put into the ERP system before serving customers (hint: this part is referring to a minimum cardinality). A customer is assisted by one and only one sales rep, and must be assigned to a sales rep. A customer can be put into the system before placing an order. A customer may place many orders, but a sales order comes from only one customer (i.e., customers do not share a sales order). An order contains at least one inventory item, but could contain many items. All items that XYZ keeps track of are not sold (some are used for maintenance of machines, etc.). An inventory item can le sold on more than one sales order. Sales orders are later invoiced Multiple sales orders can be on one invoice and there may also be partial billings (eg., sales order gets partially shipped and that shupment gets invoiced billed, then the remaining portion of the sales order gets shipped and subsequently billed on another invoice). The same applies for payments. Customers can make a partial payment (cemittance) on their invoice(s), pay an invoice in full, or a single payment can be made to apply to multiple invoices
