Why do we need structures?
Structures are required to represent statutory, regional and organizational conditions in an organization.
Allocation of employees to the structures is the first step for entering personal data.
Allocation to structures also help to find out the following:

  • Where does the employee work?
  • Which position does the employee hold?
  • How many hours in a period does the employee work?
  • Which public holidays does an employee get?
  • How is the employee paid?

    There are 3 types of structures in SAP
