Trigger events on state changes

You can configure a state flow to trigger a registered system event when a task transitions from a starting state to a specified end state. For example, you can use events to trigger email notifications and create script actions.

About this task

You can configure a state flow to trigger a registered system event when a task transitions from a starting state to a specified end state. For example, you can use events to trigger email notifications and create script actions. When you attach an event to a state flow, the ServiceNow system creates a business rule called State Flow Events for <table name> for the table specified in the state flow. If you specify a start and end state, the business rule executes when the record transitions from the start state to the end state. If the state flow only specifies an end state, the business rule executes whenever that end state is reached. The system creates one business rule for all state flows containing events on a single table. When all events or all state flows on a table are deleted, the system deletes the business rule.

To create an event that fires when a work order task moves from a starting state of Work in Progress to an end state of Closed Complete:

Procedure

  1. Register a new event on the Work Order Task [wm_task] table called task.closed.
  2. Navigate to State FlowsWork Task Flows.
  3. Open the state flow record Close Complete.
  4. Select task.closed in the Event field and save your changes.

    The ServiceNow system automatically creates a business rule called State Flow Events for wm_task.
