Organizational Object Types

An Organization plan consists of various object types, which define the grouping of similar data together. Each object type consists of a unique object key. All object types are linked together with a relationship among each other.
Example − A person holding a position that is defined by a specific job.


In an Organization plan, relationships are used to link different object types.
Example − A person holding a position in an organization and is assigned with cost center. It defines Person to position relationship and position to Organization unit.
While defining an hierarchical organization structure, you are creating a relationship between organization objects. When a person is holding a position in an organization unit, it means there is relationship between the position object and the organization object.


It determines the life of object types. At the time of object creation, you enter the start and the end time of the project and this determines the validity of the object.
There are various types of object types that can be defined in an organization plan. Given below are most common object types and their keys −
