What may cause an error when attempting to delete a grade from the system?

The ability to delete a grade from the system is contingent on several factors, particularly the presence of assignment records associated with that grade. If there are employees assigned to a particular grade, the system prevents its deletion to maintain data integrity. This ensures that historical records, reporting, and employee classifications remain consistent and accurate.

When assignment records exist, deleting the grade could lead to unresolved references in employee records, which can complicate data management and reporting processes. Thus, the system enforces this restriction to protect the integrity of the information it holds.

While the other factors related to grade rates, linking to a grade ladder, or marking a grade as inactive can be relevant in the overall management of grades, the immediate barrier to deletion comes primarily from existing employee assignments. This underscores the importance of maintaining accurate records across all related functionalities in Oracle HCM Cloud.
