C_THR81 Employee Central Core Practice Question
A SuccessFactors administrator is configuring the MDF object 'Job Code' in Employee Central. The business wants to ensure that when a user creates a new Job Code record, the 'Job Family' field is required and must be selected from a valid list. The administrator decides to use a business rule to enforce this requirement. Which business rule event type should be used to trigger the rule when a new Job Code is being created?
⚠ Common exam trap
Candidates often confuse onSave with onChange or onInit, and assuming any rule event can enforce required fields on creation.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
onSave
The onSave event is designed to validate MDF object records before they are saved. It allows the rule to check that Job Family is populated and valid, and to block the save if not. onInit, onChange, and onDelete serve different purposes and cannot enforce required field validation at creation time. Therefore, onSave is the correct choice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
onChange
Why it's wrong here
onChange fires when a specific field value changes, not on record save. While it could validate the Job Family field when it is modified, it does not guarantee validation if the field is left empty or if the record is saved without changing that field. The requirement is to enforce the field on creation, which is better handled by onSave.
- ✓
onSave
Why this is correct
onSave is the correct event type because it fires when a user saves a new or modified MDF object record. For enforcing required field validation and list selection on creation, onSave triggers before the record is committed, allowing the rule to validate the Job Family field and prevent saving if invalid. This is the standard event for validation logic on MDF objects.
- ✗
onDelete
Why it's wrong here
onDelete triggers when a record is deleted, which is irrelevant to validating required fields during creation. It cannot enforce that Job Family is selected when creating a new Job Code. Using onDelete would not prevent saving an invalid record. Thus, it is incorrect for this scenario.
- ✗
onInit
Why it's wrong here
onInit fires when the MDF object is initialized or loaded, not when a user saves a new record. It is used for setting default values or initializing fields upon object load. It cannot enforce required field validation on save because it executes before user input and does not re-trigger on save. Therefore, it fails to meet the scenario's requirement.
