Infotypes

Definition

Infotypes are units of information in the Human Resource Management System.

Use

Recording employee data for administrative, time recording and payroll purposes is the most important aim of master data administration in the HR system. In the R/3 System, the information units used to enter master data are called infotypes.

Infotypes are used to group related data fields together. Infotypes give structure to information, facilitate data entry, and enable you to store data for specific periods.

Structure

Infotypes are characterized by the following:

  • Infotype structure
  • Data entry
  • Time dependent storage of infotype data

Infotype Structure

To the user, infotypes appear as data entry screens. They contain whole series of information (e.g. last name, first name, date of birth) that you enter in data fields. Data fields concerning the same or similar subject matter are combined into data groups or information units.

In database terms, infotypes represent a data structure or set of related data records. When you update an infotype, old data is not lost but is instead stored in the system for historical evaluation purposes.

Data Entry

You enter data in accordance with the following principles:

  • Your entries are automatically checked for accuracy and against table entries.
  • Predefined default values help you to enter and maintain data.
  • Checks and default values depend on the relevant employee’s organizational assignment. The organizational assignment determines the relevant information used from time recording, wage type and pay scale structure.

Time-Dependent Storage of Infotype Data

When you update an infotype, the old data is not lost. Instead, it is retained so that past data can be evaluated. When you update an employee’s personal data, the old data is automatically time-delimited. The system creates a validity period for each infotype record. As a result, each employee infotype has several data records, which differ from each other by their validity periods.

You must also define how the various data records of one infotype interact with each other with respect to their validity periods. This time-based reaction is determined by the infotype Time Constraint.

You can assign authorizations on an infotype basis.
