Constant Nodes in Policy Designer

The Properties window for a Constant node contains the items that are described in the following table.

Item	Description	Notes
Data Type list	Specifies the type of data that the node represents.	This property is not required, but selecting a value can help catch errors and facilitate policy execution.
Value box	Specifies the value that the node represents.	If the data type for the Constant node is a Data Frame, then, on the Properties window, <DATAFRAME> appears in the Value box. You can select to access the Edit Data Frame window, in which you can view the Data Frame or configure its input values.

Consider the following nodes and connections.

In this example, the A Constant node is connected to a successor Condition node. This Condition node is also connected to another predecessor node, which is an Entity node representing the Equipment family.

As shown in the following image, you can use the Properties window for the Condition node to select the AConstant node and its value, which is A. With these options selected, the Condition node evaluates whether or not the value in the Criticality Indicator field of a specified Equipment record is A.

Regardless of the Equipment records specified via policy instances, the Condition node will always compare the value in the Criticality Indicator field to A.
