Using action rules in the web Process Designer

The following steps describe how to add a simple action rule to an existing Decision task by using the decision editor.

1. Click the Decisions tab to open the rules editor.
2. Select the your Decision task.
3. Click inside the rule window to begin creating a new rule from the template. By default, the rule editor opens with a basic template for a simple rule, with one condition (if) and one action (then). For example, you can enter the following rule definition, if expense is more than 5000 then set requireApproval to true ;.
4. Click the condition placeholder, next to if, to use the Content Assist menu to complete the condition. Click a condition statement in the menu to add that condition to the rule.
   • If the list of conditions is long, you can use the Hierarchical View menu instead of the Content Assist menu to select the condition statement. To activate the Hierarchical View, click on the Toggle Hierachical View icon while the Content Assist menu is open, or press Ctrl+Shift+Spacebar.
   • If you know the name of the condition that you want to insert, start typing the condition name. The Content Assist shows all the conditions that match the name as you type.
   • The rule can reference service flow variables, for example, expense and requireApproval.
5. To select from the menu of possible actions, click the action placeholder, next to then. Click an action statement in the menu to add that action to the rule. For more information about using the menu to select actions, refer to the related topic in the IBM Operational Decision Manager knowledge center: Inserting a term or a phrase.
6. To add additional rule parts to the rule, click to place the editor cursor above or below the existing rule content, then press Ctrl+Spacebar to activate the Content Assist menu. The Content Assist box displays a list of valid rule parts. For example, to create a definition rule part, click before the if condition section, then press Ctrl+Spacebar to open the Content Assist menu and select definitions. To create an else rule part, click below the then section of the rule.
7. To add additional rules to the decision, click one of the rule plus symbols beside the rule editor window. Each time you click a plus symbol, a rule editor window is opened. Each window contains the simple rule template.
8. In a decision that contains multiple rules, you can change the order of the rules. Click the up arrow beside the editing window to move the rule up one place in the rule order. Click the down arrow to move the rule down one place in the rule order.
9. The rule editor saves the rules periodically as you are authoring. To save all the rules in the decision while you are authoring, press Ctrl+S, or click Finish editing .
