Define a Case Expression

A Case Expression is an Expression that works as a group of if-then-else Expressions that are applied together against one Field (example: If the Incident Priority equals 1, then apply the Alert - High color to the Priority alert bar).

To define a Case Expression:

1. Create an Expression.
2. In the Editor drop-down, select Case.

   The Case Expression section opens.

3. In the If condition is true section, select a type of If statement (Simple, Advanced, or Named Expression), and then define its properties:
   1. Simple: Define an Expression (example: Incident.Priority equals 1):
      1. Select a value from the Token Selector in the left-most Value drop-down (example: Incident.Priority).
      2. Select an operator from the Operator drop-down (example: Equals).
      3. Select a value from the Token Selector in the right-most Value drop-down (example: 1).

         The If statement displays in the Cases pane.

         Note: The If statement ends with the term empty because the Then statement has not been defined.
   2. Advanced: Click the Edit button to to open the Custom Expression window, and then define a Custom Expression.
   3. Named Expression: Click the Ellipses button to access the Expression Manager, and then select a stored Expression or create a new Expression.
4. In the Then assign this value section, define the Then value (example: Alert - High):
   1. Value: Select a value from the Token Selector.
   2. Value is a color: Define a color value.
      1. Select the Value is a color check box.
      2. Click the Color Selector button to open the Color Selector, and then select an existing color or create a new color.

         The Then value displays in the Cases pane.

5. (Optional) Add related Expressions to the Cases pane (example: If the Priority equals 2, then apply the Alert - Medium color to the Priority alert bar).
6. Define a default value:
   Note: The Expression will display this value if none of the defined cases are true.
   1. Click the Default: empty row in the Cases pane.

      The Then assign this value section opens.

   2. Value: Select a value from the Token Selector.
   3. Value is a color: Define a color value.
      1. Select the Value is a color check box.
      2. Click the Color Selector button to open the Color Selector, and then select an existing color or create a new color.
