C_THR81 Employee Central Core Practice Question

A global company uses Employee Central and needs to configure a business rule that assigns a specific 'Works Council' based on the employee's 'Location' and 'Legal Entity'. The rule must run when either Location or Legal Entity changes, and it should set the Works Council field on the Job Information record. Which approach is most appropriate?

⚠ Common exam trap

The trap here is assuming that you need separate rules for each trigger field, or that an OnSave rule will provide the same immediate behavior.

Answer choices

Why each option matters

Correct answer & explanation

✓

Create an OnChange rule on Job Information with trigger fields Location and Legal Entity

A single OnChange rule on Job Information with both Location and Legal Entity as trigger fields is the most appropriate. It fires whenever either field changes, setting the Works Council accordingly. This avoids redundancy and ensures immediate updates, unlike separate rules or OnSave rules that do not trigger on field changes.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Create an OnSave rule on Job Information that evaluates Location and Legal Entity

    Why it's wrong here

    An OnSave rule would only run when the Job Information record is saved. It does not provide immediate update when either field changes. The requirement specifies that the rule must run when either field changes, implying real-time responsiveness. Thus, OnSave is not the best fit.

  • ✗

    Create a business rule on the Location object that updates the Works Council on Job Information

    Why it's wrong here

    A business rule on the Location object cannot directly update fields on Job Information because it operates in a different context. Cross-object updates require a rule on the target object or a save rule with association. This approach would not work as described.

  • ✗

    Create two separate OnChange rules: one on Location and one on Legal Entity

    Why it's wrong here

    While two separate OnChange rules could work, they would both need to set the Works Council field. This could lead to conflicts or redundant execution. A single OnChange rule with both trigger fields is more efficient and avoids potential race conditions or duplicate logic.

  • ✓

    Create an OnChange rule on Job Information with trigger fields Location and Legal Entity

    Why this is correct

    An OnChange rule on Job Information can have multiple trigger fields. When either Location or Legal Entity changes, the rule fires and sets the Works Council field. This provides immediate update and meets the requirement of reacting to changes in both fields.
