C_THR81 Employee Central Core Practice Question
A company uses Employee Central and needs to ensure that when an employee's 'Job Classification' changes, the 'Pay Grade' is automatically updated according to a mapping table. The mapping table is maintained in an MDF object called 'JobClassToPayGrade'. Which approach should the administrator use?
⚠ Common exam trap
The trap here is assuming that picklist dependencies can set values, when they only filter available options; actual value assignment requires a business rule.

Correct answer & explanation
✓
Create an OnChange business rule on Job Information that looks up the JobClassToPayGrade MDF object and assigns the corresponding Pay Grade.
An OnChange rule on Job Information triggered by Job Classification is the correct mechanism because it fires immediately when the field changes, can look up the MDF mapping object, and assign the corresponding Pay Grade. This ensures data consistency in real time and leverages the MDF object as a lookup source, which is a common pattern in Employee Central.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a picklist dependency between Job Classification and Pay Grade using the Picklist Management tool.
Why it's wrong here
Picklist dependencies control the values available in one picklist based on another, but they do not automatically assign a value to a field. They restrict choices rather than set values. Since the requirement is to automatically populate Pay Grade from a mapping table, a picklist dependency would not perform the assignment and is not the correct solution.
- ✗
Create an OnSave business rule on Employee Information that reads the Job Classification and updates Pay Grade.
Why it's wrong here
An OnSave rule on Employee Information fires when the employee record is saved, not when Job Classification changes on Job Information. It may not fire at the right time and could miss the event entirely if only Job Information is edited. The requirement is for a change-driven update, so this approach is less reliable and not the intended design.
- ✗
Use a Scheduled business rule that runs nightly to synchronize Pay Grade based on Job Classification.
Why it's wrong here
A scheduled rule would update Pay Grade only at the next run, leaving a window where the data is inconsistent. The requirement implies immediate update upon change. Scheduled rules are suitable for batch corrections but not for real-time dependent updates. This approach introduces latency and is not the best fit.
- ✓
Create an OnChange business rule on Job Information that looks up the JobClassToPayGrade MDF object and assigns the corresponding Pay Grade.
Why this is correct
An OnChange rule on Job Information triggered by the Job Classification field can query the MDF mapping object and set the Pay Grade field. This is the standard way to implement dependent field updates based on a lookup table, and it ensures the update occurs immediately when the triggering field changes.
