To achieve the desired outcome, a business rule must be configured to trigger when the 'Location' field is changed within the 'Job Information' portlet. The correct configuration is to set the rule's Base Object to 'Job Information'. The rule should then be assigned to the triggering field, which is 'Location', using the onChange event. This ensures that the rule executes immediately after a user modifies the location, allowing it to fetch the corresponding timezone from the selected Location Foundation Object and populate the 'Timezone' field in the Job Information record.

A. Base Object: Location; Assigned to Timezone field as onSave: The base object is incorrect; the rule must be on 'Job Information'. The rule is also assigned to the wrong field and uses the wrong event (onSave instead of onChange).

B. Base Object: Location: Assigned to Timezone field as onChange: The base object is incorrect. While the event is correct, the rule must be based on 'Job Information' and assigned to the 'Location' field to trigger the action.

D. Base Object: Job Information; Assigned to Timezone field as onChange: The rule is assigned to the wrong field. Assigning it to the 'Timezone' field would cause it to trigger when the timezone itself is changed, not when the location is changed.

1. SAP SuccessFactors Employee Central Documentation - Implementing Business Rules in SAP SuccessFactors: In the section "Rule Events"

the onChange event is described as being "triggered when you change the value of a field and tab out of it." This confirms onChange is the correct event for immediate field population upon change.

2. SAP SuccessFactors Employee Central Documentation - Implementing Business Rules in SAP SuccessFactors: The section "Assigning a Business Rule to a Field in an HRIS Element" details the process: "You can assign a business rule to a specific field in an HRIS element... The rule is triggered based on the event type you select." This supports assigning the rule to the 'Location' field (the trigger) on the 'Job Information' element (the base object).
