C_THR81 Employee Central Core Practice Question
A company uses SAP SuccessFactors Employee Central and has a requirement to track employee language skills. Each employee can have multiple language skills, and each skill must include the language, proficiency level, and a certification date. The company wants to maintain a history of changes to these skills. Which MDF object configuration should be used?
⚠ Common exam trap
The trap here is assuming that a picklist or standalone object can handle multiple entries with history, when a child MDF object with effective dating is required.
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
✓
Create a child MDF object for Language Skills with a composite association to the Employee object, and enable effective dating.
A child MDF object with a composite association to Employee and effective dating enabled allows multiple language skills per employee, stores detailed attributes, and maintains a history of changes. Other options lack the necessary structure or history tracking.
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 a picklist for Language Skills and assign it to a field on the Employee object.
Why it's wrong here
A picklist can only store a single value per field and does not support multiple entries with additional attributes like proficiency level and certification date. It also does not track history. Therefore, a picklist is insufficient for this requirement.
- ✗
Create a standalone MDF object for Language Skills and use a business rule to associate it with employees.
Why it's wrong here
A standalone MDF object without a composite association to Employee would not inherently link multiple records to a single employee. While a business rule could create associations, it would not provide the same seamless data model as a child object. This approach is more complex and does not guarantee history tracking.
- ✓
Create a child MDF object for Language Skills with a composite association to the Employee object, and enable effective dating.
Why this is correct
A child MDF object with a composite association to Employee allows multiple language skill records per employee. Enabling effective dating maintains a history of changes. This configuration exactly meets the requirements of multiple skills, detailed fields, and historical tracking.
- ✗
Create a generic object for Language Skills and use a many-to-many association with the Employee object.
Why it's wrong here
While a many-to-many association could link employees to language skills, it does not support effective dating or history tracking natively. Additionally, generic objects are not the standard for employee-related data in Employee Central; MDF objects are preferred. This option does not fully meet the requirements.
