Payroll files contain data for payroll and payroll results.

The system requires the following files for payroll:

• Pnnnn (nnnn = number of the infotype)
  The Pnnnn files contain data that has been entered in the respective infotypes for an employee.
• PCL1
  The PCL1 file contains primary information, in other words, data from the master data and time recording systems.
• PCL2
  The PCL2 file contains secondary information, in other words, derived data and all generated schemas.

When you start payroll, the system imports the relevant master data from the Pnnn files (for example, basic pay and tax class) and imports the time data from the PCL1 file to the IT table. The system imports the payroll results from the previous month from table ORT (for example, to form averages). The system processes this data and saves the payroll results and generated schemas in the PLC2 file.
