Distributed HR
Master Data 
Use
You can use Organizational Management and Personnel Administration in separate HR systems and integrate the two components at the same time.
As a result:
- An organizational plan is created in a global HR system (corporate system) using the Organizational Management component.
- This organizational plan is replicated in one or more regional HR systems (operational systems).
- The Personnel Administration (and Recruitment and Payroll) components are implemented in these regional systems, where persons are related to the positions in the organizational plan.
To ensure that the data in Organizational Management and the data in Personnel Administration remain consistent:
- Change pointers are written for organizational units, positions, and jobs whose original system is the global system each time that data is changed so that such changes are replicated in the regional systems.
- Change pointers are written for persons whose original system is one of the regional systems each time that data is changed so that such changes are replicated in the global system.
- Change pointers are written for relationships between persons and positions whose original system is one of the regional systems each time that data is changed so that such changes are replicated in the global system.
- ALE inbound processing integration is automatic, which means you are not required to execute reports RHINTE10 and RHINTE30.
