Creating a workflow object
A workflow object is a reusable object in Data Services. Once created, the same object can be used in different places of your ETL code. For example, you can place the same workflow in different jobs or nest it in other workflow objects by placing them in the workflow workspace.
Note that a workflow object cannot be nested inside a dataflow object. Workflows are used to group dataflow objects and other workflows so that you can control their execution order.
Every workflow object has its own local variable scope and can have a set of input/output parameters so that it can "communicate" with the parent object (in which it is nested) by accepting input parameter values or sending values back through output parameters. ...
