Adding a one-to-one mapping

Once you have defined your source and target, you can add a one-to-one output mapping in the following way 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. If you need to define further 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 all the remaining source values to target values, repeat steps 1 to 3.
An alternative method for adding a one-to-one mapping is:
  1. Select the mapping source and target values that you want to map.
  2. Right-click the selected values and select Create Mapping from the pop-up menu.

In the Compose Expression editor, you can add mapping expressions for sources and targets that have not yet been defined, but you cannot change mapping targets.
