Product Administration Guide > Configuration Rule Template Reference >
The Display Message template has the following form:
[Item or condition] displays this rule's explanation
The Display Message template is one of two ways to communicate messages to the user. The other is the Display Recommendation template.
In the Display Message template, when the condition is true, the explanation you entered for the rule is displayed to the user in the Message area. The explanation must describe the condition in the rule and can add additional information.
Use the Display Message template to display messages when a defined condition is true.
For example, you write the following Display Message rule:
When [Product A is selected], display this rule's explanation.
You then save the rule and enter the following in the Explanation field:
Product A has been selected. You can purchase only two of these items.
During a configuration session, when the user selects Product A, the rule explanation appears in the message area.
