Adding a one-to-many mapping

One-to-many mappings are made in the same way as many one-to-one mappings. You can add a one-to-many output mapping in the following way from the Source view, having defined your source and target:

  1. Click the source message element that you want to map and drag it into the Target view, dropping it onto the target element that you want to use. The mapping appears in the Overview view showing the Source, Target and Target Value.
  2. If you need to further define the way that an assignment is made, click the Target Value for that assignment, and then click the box that appears at the end of the row. The Compose Expression editor appears and you can qualify your assignment. See Configuring a mapping.
  3. When you have completed your actions on this screen, click OK. You are returned to the Overview view.
  4. To assign the source to more target values, repeat steps 1 to 3.
An alternative method for adding a one-to-many mapping is:
  1. Select the mapping source and target value that you want to map.
  2. Right-click the selected value and select Create Mapping from the pop-up menu.
