The following steps describe how to delete source and target
elements using the Message Mapping editor:
To delete a source path, modify the expression so that it no longer
uses the source value to compute the target.
If this is the
last use of the source path, the line linking the source and target is removed.
If the expression no longer has any value, the target becomes unmapped.
To delete a target from the Edit pane,
click the target and click Delete.
The
target structure is preserved if possible. If you delete a 'for', 'if', 'condition'
or 'else' row, clicking Delete removes the single row.
To delete a database source, click the SELECT statement then remove
all references to the source manually. Alternatively, delete the
SELECT source in the Source pane then remove
all references to the source manually.
To delete a database target, delete the INSERT, UPDATE
or DELETE statement. Alternatively, update or delete the statement
in the Target pane.
