Add an Expression to a Policy

You can create a Boolean expression and add it to a policy. Boolean expressions operate on variables, and the values of the variables at the time that the policy is processed affect the outcome of the processing. Thus, Boolean expressions influence policy decisions.

To add an expression to a policy

1. Click the Expression tab on the Policy pane.

   The Expression group box opens.

2. Click Edit.

   The Policy Expression pane opens.

3. Type variable names in the fields on the Condition group box, or click Variable Lookup, select an operator from the drop-down list, and click Add.

   The condition is added to the Infix Notation group box.

   Note: To create multiple conditions, repeat this step.

4. Select the conditions and click the buttons on the Infix Notation group box to create an expression.
5. Click OK.

   The Expression group box reopens, and the expression is displayed in the field on the group box.

6. Click Submit.

   The Modify Policy task is submitted for processing.
