SAP R/3 Human Resource Overiew

The "Distributed HR Master Data" scenario enables you to integrate the Organizational Management and Personnel Administration components, even though they are in separate HR systems. This means that:
An organizational plan is maintained 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 component (as well as the Recruitment and Payroll components) are implemented in these regional systems, where persons are related with positions in the organizational plan. HR master data in Personnel Administration is replicated from the global systems to the global system.

Integration The following functions enable objects from Organizational Management, Personnel Administration, and Recruitment to be distributed and kept consistent in the various systems:
Functions in the Global System
The organizational plan is created and maintained with organizational units (object type O), positions (object type S), and jobs (object type C). Therefore, the global system is the original system for these objects, and bears business responsibility for them.
The data is distributed to the regional systems.
Each time data is changed for organizational units, positions, and jobs whose original system is the global system, change pointers are written so that the changes can be replicated in the regional systems.

Functions in the Regional Systems
Persons (object type P) and applicants (object type AP) are created and maintained. Therefore, the regional system concerned is the original system for these objects, and bears business responsibility for them.
The organizational plan exists as a replication from the global system.
Relationships are created and maintained between persons and (replicated) positions.
The data (persons, applicants, and relationships) is replicated to the global system.
Each time data is changed for persons and applicants whose original system is one of the regional systems, change pointers are written so that the changes can be replicated in the global system.
Each time data is changed for relationships between persons and positions whose original system is one of the regional systems, change pointers are written so that the changes can be replicated in the global system.
Further HR functionality (such as Payroll) is used.

If you require information on replication data flows for objects and relationships, you can use the SAP Data Flow section in Distributed Organizational Management.
