Basic concepts of applying For-Each function

The attached document provides a conceptual overview on how to apply For-Each function to filter records, join multiple sources and finding deltas between two data sets.

What is For-Each?

The For Each property is used to repeat the occurrences of a target element or node, depending on the total occurrences of a source element or a node in the source file.
For example, an XML schema with a node customer has three elements, first_name, last_name, and state. This schema is used both at the source and at the target end.

Supposing, the source file has 10 occurrences of the customer. Applying the For Each property on the target node customer, for the source node customer, generates an output file containing 10 occurrences of the customer in it.
