How will you use SEQUENCE as the Target of a BRANCH? |
|
Answer» There MAY be times a BRANCH step is needed if you want to conditionally run/execute a series or number of multiple STEPS instead of just one (single step). In such cases, you can utilize or use the SEQUENCE step as the target step and group a series of flow steps below it (beneath). Example: An example is GIVEN below in which a service accepts a PURCHASE order. Based on the payment type specified in the PaymentType variable, the purchase order is processed in one of three ways. Since each PO (purchase order) requires a series of steps to be completed, the targets of the BRANCH are designated as SEQUENCE steps, and the appropriate set of flow steps is listed as a child of each SEQUENCE (children beneath each SEQUENCE). Consider the SEQUENCE step as the target of a multi-step ALTERNATIVE Describe a multi-step alternative in a sequence |
