  2. In the XML tree view of the Customer output table, right-click the customer (loop) node and select Delete from the contextual menu.

  6. Right-click the customer node in the output table and select Create Sub-Element from the contextual menu. In the pop-up dialog box, enter the name of the new sub-element. In this example, it is Name.
  7. Click OK to validate the changes and close the dialog box. A Name node is added under the customer node in the output table.
  8. In the row1 main input table, select the id and CustomerName nodes and drop them onto the Name node in the output table. In the pop-up dialog box, select Create as sub-element of target node and click OK to close the dialog box. A id node and a CustomerName node are added under the Name node in the output table.
  9. In the output table, right-click the Name node and from the contextual menu select As loop element to set it as the loop element, then right-click the customer node and from the contextual menu select As group element to group the output data according to the LabelState element.
  10. Click OK to validate the changes and close the map editor.
  11. Press Ctrl+S to save the Job and then F6 to run the Job.
