You can assign a default value for a destination node
in a map. A destination node of a map is displayed in the mapping
pane. The following figure shows the To Orchestration pane. How the
default value is used during run time depends if a link is assigned
to the destination node as described in the following cases:
- Define a default value for a destination node that does not have
a link from a source node or function as shown in the following figure:
For this case, the specified
constant value is always assigned to the destination node during run
time.
- Define a default value for a destination node that has a link
from a source node or function as shown in the following figure:
For this case, the specified
value is only assigned to the destination node, if the link from the
source node or a function to the destination node does not provide
a value for the destination node during run time.
You can also use configuration properties to supply the
default values for destination nodes of a map of a mapping pane as
described in step 2 of the following procedure. You must create
the configuration property before defining the default value
as described in the following procedure.
To define a default
value for a destination node:
To clear the default value for a destination node:
- Right-click a destination node with a default value assigned to
the node within the mapping pane. A destination node with a value
assigned shows the default (
) icon to the left of the node.
- Select the Define Default Value option
from the list. The Define Default Value dialog
box opens with the text or the selected configuration property highlighted.
- Press the Delete key.
- Click OK. The default (
) icon
is removed from the destination node in the mapping pane.
