A Group statement links a complex source element to a complex target element. You can nest other statement types as children of the Group statement.
You can use a Group statement to provide a common context for all the child statements to pass or fail simultaneously. You can also use a Group statement to help you organize or simplify other statements.
For example, you want to map an Employee parent element in the source schema to a Worker parent element in the target schema where both parent elements contain nested child elements such as FirstName and LastName. You can create a Group statement to map the Employee parent element to the Worker parent element, and you can create nested Map statements to map the child elements of the Employee parent element to the child elements of the Worker parent element.
The following image shows the how the elements are mapped in a hierarchical mapper:
