Triggering a Business Process from Rules

This topic describes the procedure to trigger a business process from rules.

You can trigger a business process from a rule using the Trigger Business Process option in a rule modeler. For instance, let us assume that a customer has placed an order. On inserting the Order, a rule is triggered, which checks whether the items exist in the inventory. If the items do not exist, the transaction should abort. If the items exist, the order processing business process is triggered.

1. Depending upon how you access a document, creating a rule and accessing the business object can be done in various ways. Refer to Accessing the Rule Modelerfor more information.
2. Set the properties of the rule on the Properties tab. For more information on the various fields on the rule properties interface, refer to properties of a rule.
3. Click the Behavior tab to define the rule's behavior. For more information, refer to Defining Rule Behavior.
