State flow customization

Summary of State Flow Customization
State flows in ServiceNow control the transitions between states in Service Management applications. Administrators can customize these flows by adding or deleting states, triggering events, and managing transitions, both automatically and manually. Custom state flows require scripting knowledge and specific user roles for access and manipulation.

Key Features
- Manual and Automatic Transitions: Use UI actions and business rules to initiate state changes based on specified conditions.
- Custom Transitions: Tailor the order of state changes for requests and tasks.
- Field Controls: Manage visibility and behavior of fields during state transitions.
- State Choice List: Limit available states based on valid transitions for enhanced user experience.
- Trigger Events: Configure events to activate when state transitions occur or specific end states are reached.
- State Flow Dictionary Overrides: Define starting states for new records in extended tables.
- Work Notes: Utilize work notes to document information related to state transitions.
- Rebuild and Cleanup: Rebuild state flows when there are sysid mismatches and clean up unnecessary elements when state flows are deleted.
Key Outcomes
By effectively using state flows, ServiceNow customers can ensure a streamlined process for managing the lifecycle of requests and tasks, enhance control over record transitions, and improve communication through work notes and event triggers. This customization allows organizations to adapt the system to their specific operational needs and improve overall efficiency.
State flows control the sequence in which records transition between states in Service Management applications.
- Add or delete states.
- Trigger events on particular state transitions.
- Transition to another state automatically when data in a request or its task changes, or change states manually when the user clicks a button.
- Limit the choice list for the State field to those end states that are valid transitions from the given start state.
- Control the visibility and behavior of selected fields on a target table when records in that table change states.
- Create custom state flows. Turn off the State flows are enabled option on the configuration screen. Creating custom state flows requires scripting knowledge.
How SM request and task state flows work
State flows replace the standard process that controls how requests and their associated tasks move between states. The ServiceNow system creates business rules, client scripts, and UI actions that perform the transitions and field controls you specify. These programming elements remain in use while the state flow records that use them are present. When state flows on an SM application table are deleted, the system attempts to delete any unnecessary programming elements that were created on that table. You can limit the selections for the State field to valid states for the transition, based on the starting state.
- Manual transitions:A UI action, created automatically by the system when you provide a condition or a script, initiates a transition.
- Automatic transitions:A business rule, created automatically by the system when you provide a condition and a script, initiates a transition when changes are made to a request or task.
Features available with state flows
- Custom transitions: Customize the order in which states can change for requests and task records.
- Field controls: Control the behavior and visibility of specific fields when a task changes states or reaches a specified end state.
- State choice list:Limit the values offered in a task record State field to valid states for that transition. This is the same client script that the system creates to manage field controls for state transitions.
- Events:Trigger events when a state transition occurs or when a record reaches a specific end state.
Start and end states
You can create a custom state flow for processing that must occur when a task record makes a specific transition from one state to another. These records require a starting state and an ending state, and processing occurs during the transition between states. To perform some processing when a task record reaches a particular end state, you only need to define the end state. In some cases a state flow can have a starting state only, such as when you need to perform some type of cleanup after a task is canceled. A state flow might have no starting or ending state if the processing in the record applies to more than one state transition.
The solution is to store the business rule or client script in a state flow record and create a condition to trigger processing for any state change that requires it. An example of this in field service management is the Roll Up Changes business rule on the Work Order Task [wm_task] table. This business rule rolls up state changes that occur in tasks to the parent work order.
