Using a Literal to Populate Target Elements

You can add a Literal node, enter the literal value, and link the Literal node to one or more targets. This hard codes the literal value into the target.

Alternately, you can use a constant to populate a target inside a transformation expression by creating a map link, clicking the map link, adding a constant to the Transformation Rule Expression canvas, and then wiring the constant to the target.

To add a literal:

Double-click to expand a target schema node.
Right-click in the Map canvas and choose Add Literal.
Click the Literal (literal_n) node to edit the Literal Properties in the Properties Panel view.
Literal properties
Field Explanation and options
Name Automatically named literal_n. Edit as necessary.
Literal Value Enter any string or constant to be assigned to the target, for example, -256.125.
To link the Literal to a target, click the Literal node's connection point, which is either a yellow or green dot, then click directly on the target name, for example, Month12 [xsd:integer]. Repeat for each target that receives the literal value.
A map link, which is a blue arrow, is created and connects the Literal to the target.

Field	Explanation and options
Name	Automatically named literal_n. Edit as necessary.
Literal Value	Enter any string or constant to be assigned to the target, for example, `-256.125`.

Click the Literal map link to edit the Link properties in the Properties Panel view:

Link properties

Field	Explanation and options
Source literal	Displays the name of the literal node, for example, `literal_4`, as defined earlier in Literal properties.
Target full path	Displays a string identifying the target schema, element, and attribute (optional), for example, `/sy2:OrderSummary/sy2:OrderRef`.
	Path field	Explanation
	sy2	An arbitrary namespace identifier.
	OrderSummary	The name of the schema's root node.
	OrderRef	The target, in this case, an element.
Target relative path	Displays a string identifying the target without the schema qualifier, for example, ../`ParallelAttributeInSameElement`.
Output as CDATA	Character Data (CDATA) defeats the standard XML encoding rules for `&` (ampersand), `>` (greater than), and `...` (ellipsis), allowing the literal data to bypass the XML parser. Select Yes to encode the literal inside a CDATA section. That is, the literal is wrapped between the delimiters `<![CDATA[` and `]]>`.
Test	Enter the test condition that defines the condition on which the target is created. For example, `/sy2:OrderSummary/Sy2:OrderRef!="` checks the presence of input values during runtime and omits the target in the resulting XML document if Sy2:OrderRef is empty (null).
