Conversely,if a customer orders goods that are not in stock,process 1.1 runs a special back order routine.This routine determines the inventory requirement necessary to satisfy the order and then sends the back order request to the purchasing department.This activity is depicted by the "Back order" data flow,which in reality is a specific type of exception routine (i.e. ,a specific type of reject stub).If the customer refuses to accept a back order,then the sales event is terminated and the order is rejected,as shown by the "Reject" data flow.Information from the order (e.g. ,sales region,customer demographics,and order characteristics that reflect buying habits)that has potential value to marketing is recorded in the marketing data store.
