Example of When to Use a MAP Step
*You want to assign an initial set of input values in a flow service (that is, to initialize variables). You insert the MAP step at the beginning of the flow, and then use the Set Value modifier to assign values to the appropriate variables in Pipeline Out.
*You want to map a document from one format to another (for example, cXML to XML). Insert transformers into the MAP step to perform the needed data transformations.
