Processing HR Master Data

A variety of functions is available for editing and managing employee data.

You can change existing infotype records and create new infotype records for employees. The SAP system uses this data to create a history of all the changes and developments pertaining to anemployee during the period that the employee works at a company.
- Create infotype record
  
  The Create function allows you to enter new data. A new record is created while retaining the old record. The infotype history is generated by defining the validity periods.
- Change infotype record
  
  The Change function enables you to correct an existing infotype record without creating a new one. You overwrite the old one. When an infotype record is changed, its history is not updated.
- Delete infotype record
  
  The Delete function enables you to delete existing infotype records from the database. If you delete infotype records with time constraint 1, the previous record is automatically extended. An infotype history is created using the definition of the validity period.
- Copy an infotype record
  
  The Copy function also creates new infotype records. It also updates the infotype history. Unlike the Create function, you do not enter data on an empty screen, but on a screen containing the current data. You can then overwrite these values.
So that you can simultaneously store several infotype records, you must define time relationships between the records. This is accomplished by the system using time constraints. For more information, see Time Constraints in HR Master Data .
