In ServiceNow, a workflow context refers to a specific instance of a workflow execution. When a workflow is initiated—whether by inserting or updating a record, triggering an event, or through scripts—the system creates a workflow context. This context is derived from a particular version of the workflow and is responsible for executing the defined activities and following the specified transitions within that workflow.

Key points about workflow context:

Instance of Execution: Each time a workflow runs, a new context is created to manage that specific execution instance. This allows multiple instances of the same workflow to operate independently and simultaneously.

Execution of Activities: The context manages the progression through the workflow's activities, ensuring that each step is executed in the defined order and under the specified conditions.

Tracking and Management: Workflow contexts enable administrators to monitor the state and progress of workflow executions. They provide visibility into which activities have been completed, which are pending, and any transitions that have occurred.

For example, if a workflow is designed to handle approval processes, each time an approval is initiated, a new workflow context is created to manage that particular approval instance. This context will track the approval's progress, manage notifications, and handle any branching logic defined in the workflow.

 Tables that extend a table inherit the parent’s fields. Extending a table means creating a child table that shares the same columns and business logic as the parent table. For example, the Incident table extends the Task table, which means that all fields defined on the Task table are also available on the Incident table. Extending a table allows for reusing existing fields and behaviors without duplicating them on multiple tables. Reference: Table extension and classes
