What distinguishes person numbers from worker numbers in Oracle HCM?

In Oracle HCM, person numbers serve as unique identifiers assigned to individuals when their records are created within the system. This uniqueness is crucial as it allows for accurate tracking and management of employee data across various HR processes. The person number remains consistent regardless of the individual's employment status or changes in position, making it foundational for any HR-related activities.

In contrast, worker numbers are assigned specifically to individuals actively engaged in work and may change if the individual's employment circumstances change, such as moving between roles or departments, or if they leave and rejoin the organization. Therefore, while a person may have one person number throughout their lifecycle, they could potentially have multiple worker numbers if they enter and exit the workforce multiple times.

This distinction highlights the importance of person numbers in uniquely identifying individuals across the entire system, which plays a critical role in maintaining data integrity and for reporting purposes within Oracle HCM.
