Business Rules run server-side, so the correct APIs come from the GlideSystem object (gs) rather than client-side objects like g_form. In server-side scripting, the platform provides a standard way to retrieve the currently logged-in user’s identity. The method gs.getUserID() returns the sys_id of the user associated with the current session. This is commonly used in Business Rules for auditing logic, conditional processing, field stamping (for example, setting a custom “last processed by” field), or enforcing business rules based on user identity. The g_form object is a client-side API available in Client Scripts and UI Policies, so any option using g_form is invalid in a Business Rule context. Likewise, gs.getUserSysID() is not the documented method name for this purpose. Using the correct server-side API ensures the script executes reliably regardless of UI context (classic UI, workspace, mobile), because it relies on the session and not on the form rendering layer.

 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
