Define a Logical Expression

A Logical expression uses one or more conditions (example: Incident.Status does not equal Closed) to return a true or false value.

To define a Logical expression:

Create an expression.
In the Editor drop-down list, select Logical.
The Logical Expression section opens.
Define the expression condition:
1. Select a value from the Token Selector in the far left Value drop-down list (example: Incident.Status).
2. Select an operator from the Operator drop-down list (example: Not Equal).
3. Select a value from the Token Selector in the far right Value drop-down list (example: Closed).
  If the field is validated, the Legal Values button displays to the right of the drop-down list. Use it to choose from a list of appropriate values.
(Optional) Add additional related expressions:
When you add additional expressions to the Logical expression, all conditions in the group must be true for the expression to return a True value.
1. Select Advanced.
  The Advanced section opens and displays the defined expression.
2. Define a Group expression:
  1. Select New, and then select Group Expression in the drop-down list.
    The Grouping section opens.
  2. Select a grouping condition:
    - All of the items in the group must be true.
    - At least one of the items in the group must be true.
    The grouping condition displays in the Advanced section.
(Optional) Define an expression that meets the Group expression condition:
1. Select a value from the Token Selector in the far left Value drop-down list (example: Incident.Status).
2. Select an operator from the Operator drop-down list (example: Not Equal).
3. Select a value from the Token Selector in the far right Value drop-down list (example: Resolved).
  If the field is validated, the Legal Values button displays to the right of the drop-down list. Use it to choose from a list of appropriate values.
(Optional) Add additional Logical and Group expression conditions.
Select Save.
