Adding a one-to-many mapping

Before you start:
Define your source and target by following the instructions in any of the following topics:

One-to-many mappings are made in the same way as many one-to-one mappings. This topic describes how to add a one-to-many output mapping from the Source view.

  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. 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.
  3. Click OK to return 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 click Create Mapping.
