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.
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.
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.
Click OK to
return to the Overview view.
To assign the source to more target values, repeat steps 1 to 3.
An alternative method for adding a one-to-many mapping is:
Select the mapping source and target value that you want to map.
Right-click the selected value and click Create
Mapping.
