C_THR81 Employee Central Core Practice Question
An administrator is configuring the Employee Central 'Employment Details' object. The company wants to track the employee's original hire date, which should never change, and also a 'Seniority Date' that is calculated based on the original hire date and any breaks in service. Which two configurations are required to meet these requirements? (Choose two.)
⚠ Common exam trap
The trap here is assuming standard fields like Hire Date can serve as immutable original hire date, or that picklists can handle date calculations.

Correct answer & explanation
✓
Create a business rule that calculates 'Seniority Date' based on 'Original Hire Date' and service breaks.
To track an immutable original hire date, a custom read-only field is needed because standard fields can change. For Seniority Date, a business rule is the correct tool to calculate it based on the original hire date and service breaks. Together, these configurations meet the requirements without relying on inappropriate mechanisms like picklists or Data Dictionary calculations.
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 for 'Seniority Date' with predefined values.
Why it's wrong here
A picklist is for selecting from predefined options, not for calculating dates. Seniority Date is a date value that must be derived from other fields, so a picklist is inappropriate. It would not provide the dynamic calculation needed and would require manual selection, which is error-prone.
- ✓
Create a business rule that calculates 'Seniority Date' based on 'Original Hire Date' and service breaks.
Why this is correct
A business rule is required to calculate the Seniority Date dynamically, considering the Original Hire Date and any breaks in service. This allows the system to automatically compute the date whenever relevant data changes, ensuring accuracy and reducing manual effort. The rule can incorporate complex logic for service breaks.
- ✓
Create a custom field for 'Original Hire Date' and set it as read-only after initial entry.
Why this is correct
A custom field for Original Hire Date is necessary because the standard hire date may be updated in rehire scenarios. Making it read-only after initial entry ensures it remains unchanged, preserving the original hire date. This is a common practice to maintain historical data integrity without relying on standard fields that can be overwritten.
- ✗
Use the standard 'Hire Date' field and configure it as read-only.
Why it's wrong here
The standard Hire Date field is used by the system for various processes and may be updated during rehire or other events. Making it read-only could break necessary updates and does not guarantee it represents the original hire date. It is not suitable for tracking an immutable original hire date.
- ✗
Use a standard field for 'Seniority Date' and set it as a calculated field via the Data Dictionary.
Why it's wrong here
The Data Dictionary does not support calculated fields in Employee Central. Calculations are performed via business rules, not through the Data Dictionary. While some fields may have system-calculated behavior, custom calculations require business rules. This option misrepresents the platform's capabilities.
