Employee information is broken down into different types of data, for example name, address, and basic pay. This information is stored on infotypes based on the type of data. For example, personal data is stored on the Personal Data Infotype 0002 and includes details such as first and last name, date of birth, and marital status. Information on the pay of an employee is stored on the Basic Pay Infotype 0008 and it includes salary, hourly rates, and premiums, for example. Infotypes can be created, updated, changed, and deleted and each infotype record has a validity interval or key date.
Personnel Administration
There are several ways to maintain employee data on infotype records.

Different ways to process infotypes records include the following:
Display HR Master Data (PA20)
The single screen infotype display with transaction PA20 includes the display of individual infotypes. This enables you to select only one employee and only display one infotype for them. For example, you want to look up the bank name of an employee.
Maintain HR Master Data (PA30)
The single-screen infotype display with transaction PA30 includes the maintenance of individual infotypes. This means that you can only select one employee at a time and maintain only one infotype at a time. For example, you want to change or create a new permanent residence for an employee.
Fast Entry (PA70)
Fast entry (PA70) enables you to maintain one infotype for more than one personnel number at the same time. For example, you want to pay out a Christmas bonus for all employees in the company.
Screen Overview Data Maintenance

You can store all types of information about an employee in Human Resources infotypes. They provide information with a structure, facilitate data entry, and enable you to store data for specific periods.

These are the following:
- Display HR Master Data (PA20)
- Maintain HR Master Data (PA30)
