This interface can be used by other applications to import external wage components into the SAP-HR Payroll system. The external wage components are processed in Payroll according to the Customizing settings for the accompanying HR wage type (for example, tax calculation) and are then stored in the payroll result. They are then available for subsequent processing steps (for example, payment, posting to Accounting).

The application that transfers the external wage components is described in the the following documentation as Third-Party Application.

• WageType.GetList
• PrimaryWageType.GetListExt
• PrimaryWageType.GetDetailExt
• PrimaryWageType.GetDetailedListExt
• PrimaryWageType.RegisterExt
• PrimaryWageType.UnregisterExt

• The business object EmpWageComponentExt (External Employee Wage Component) is available with the following methods for the transfer of data and the accompanying checks:

• EmpWageComponentExt.Create
• EmpWageComponentExt.Change
• EmpWageComponentExt.Delete
• EmpWageComponentExt.GetDetail
• EmpWageComponentExt.GetList

For information on the business objects and the methods, see the BAPI Explorer under Payroll ® Payroll: General Parts.

Processing of external wage components is only possible for personnel numbers whose master data is maintained in the SAP HR System.

If possible, the third-party application should only transfer results to HR if they are to be taken into account in the next payroll run. This means that data is less likely to be changed after being transferred, thus avoiding retroactive accounting runs and the need for manual processing in HR.

The third-party application should transfer your external wage components to HR in as summarized a form as possible. We recommend that you only transfer one external wage component per payroll period for each employee and wage type and that you also keep the number of wage types as small as possible.
