To set the value of a target element to a constant:
- In the Message Mapping editor Target
pane, right-click the target element or attribute and click Enter
Expression.
If the target element or attribute
has a default value, this value is added to the Edit pane.
- Enter the required constant in the Edit pane and click Enter. When entering the constant, observe the following criteria:
- Enclose string element values in single quotes.
- Enter numeric element values without quotes.
The Spreadsheet pane is updated with the value that
you have defined.
You cannot set a value for a simple element if one of its ancestors
also has a mapping. For example, you cannot map Properties from source to
target, then set a value for Properties/MessageFormat.
