Learn Organizational Management (OM) in SAP HR

In this tutorial we will cover the key concepts in the OM module of SAP HR

  • Object Types Entities within OM are maintained as object types (e.g. Org Units, positions,jobs)
  • Relationships Links objects together (e.g. person to position, position to Org Unit)
  • Validity Dates Validates life span of objects
  • Infotypes Data input screens used to record relevant information

    1. Object Types
    Each aspect of OM is recorded as an object type, a way of grouping similar data together. For example, organizational unit is an object type, position is another object type.

2. Relationships
There are many objects within OM, and the creation of relationships is the way that data is linked together. When you build the hierarchical organizational structure, you are creating a relationship between organizational unit objects. If you attach a position to an organizational unit, you are creating a relationship between the position object and the organizational unit object.

3. Validity Dates
Whenever you create an abject or a relationship between objects, you must enter start and end dates. These validity dates ensure that data entries can only be made within a specified lifespan.

4. Infotypes
These are the data input screens used to record the OM information. Some infotypes are automatically updated ‘behind the scenes’; other infotypes require you to manually input the information.
Lets look into the different OBJECT TYPES in detail
OM is based upon the use of Object Types and Relationships. Object Types group similar data together. Although an organizational plan can consist of many object types, the five basic building block object types and their ‘codes’ are as follows:

  • The Personnel Administration (PA) module of the SAP HR system holds the person related data in infotypes in the master data file.
  • The Organization Management (OM) module looks at the organization’s departmental structure and holds the data in object types. OM object types are a way of grouping similar data. The system assigns a code for each object type.
  • These objects are created and maintained separately and are then linked together using relationships.

Organizational unit

Learn Organizational Management (OM) in SAP HR

  • Object type O is used for Organizational Unit.
  • Organizational units are units of your company that perform a function.
  • These units can be departments, groups or project teams, for example.
  • You create the organizational structure of your company by relating organizational units to one another.
  • The organizational structure is the basis for the creation of an organizational plan.

Position Learn Organizational Management (OM) in SAP HR

  • Object type S is used for Position.
  • Positions are used to distribute tasks to different positions and to depict the reporting structure in your organizational plan.
  • Positions are concrete and are held by employees in a company.
  • Positions are assigned to organizational units and can inherit characteristics from a job.

  • Object type C (classification) is used for Job.
  • Positions are held by people in the company (e.g. secretary in the marketing department,HR manager). Jobs, in contrast, are classifications of functions in an enterprise (e.g. secretary, manager), which are defined by the assignment of tasks and characteristics.
  • Jobs serve as job descriptions that apply to several positions with similar tasks or characteristics. When you create jobs, they are listed in a job catalog.
  • When you create a new position (e.g. secretary in the marketing department), you can relate it to a job that already exists in the job index (e.g. secretary). The position then automatically inherits the tasks and characteristics of the job. This significantly reduces data entry time, as tasks and characteristics do not have to be assigned to each position separately, instead they are inherited via the descriptive job. Note however, that specific tasks and characteristics can also be assigned directly to positions.

    Jobs are also important in the following components:

  • Personnel Cost Planning
  • Career and Succession Planning
  • Compensation Management
    When you create jobs, they are listed in a job catalog. A job catalog is a list of jobs maintained for an enterprise.

Cost Center

  • Object type K is used for Cost Center.
  • Cost centers are a Controlling/Finance item that represents the origin of costs. Cost center are external from OM and will be created and maintained in the Controlling module. Cost centers can have relationships with either organizational units or positions.
  • Cost center assignments are inherited along the organizational structure.


  • Object type P is used for Employee.
  • A person is generally an employee in the company who holds a position.
  • Additional information for employees is maintained in PA (e.g. address, basic pay, etc.).IT0001 (Organizational Assignment) contains the position assignment, defining job,organizational unit, and cost center assignment.

    Other noteworthy Object Type is TASKS

  • Object Type T is used for tasks
  • Tasks are individual duties and responsibilities that must be undertaken by employees

    Tasks can be clubbed under two headings

  • As part of workflow
  • As part of personnel management to describe jobs and positions
