Unit 1: Creating an Organizational Structure 
An organizational plan consists of the organizational units that exist in the company. The organizational units are related one to the other in a hierarchical reporting structure. However, they can also be created independently of each other.
To create a new organizational plan, you create a root organizational unit. This is the highest unit within the organizational structure, such as the Executive Board. You then set up the organizational structure, starting at the root organizational unit and working downwards.
Procedure
Creating a Root Organizational Unit
This takes you to the Create Organization and Staffing (Workflow) screen. This user interface is divided into four screen areas:

Abbreviation: <ini
_org >Name: < Organizational plan (ini)>
The root organizational unit you have just created is then selected in the overview area.
Creating further organizational units
Starting from the root organizational unit, you create subordinate organizational units. In this unit, you will create two further organizational units.
A new organizational unit is now created below the root organizational unit.
Abbreviation: <ini
Name: <Sales ( ini )>

When determining the validity period of objects and relationships, the system chooses the validity period of the superordinate object as standard.
If you want to change the validity period for the organizational units to be created and their relationships, change the values in the corresponding input fields in the details area.
A new organizational unit is now created below the root organizational unit.
Abbreviation: <ini
_org_rd >Name: <Research and development ( ini )>

You can also include existing organizational units in your organizational plan. To do so, drag them from the selection area to your organizational plan.
Reassigning organizational units
If changes are made to the organizational structure of your company, you can reassign the organizational units involved.

If you reassign organizational units, please note the following:
Delimiting organizational units
You delimit organizational units if you want to change their validity period, that is, bring forward the validity end date.

When you delimit objects (in this case, organizational units), all of the associated links are automatically delimited at the same time.

You can only change a period if you also change a different entry of the organizational unit at the same time. For example, change the description.
