Transferring external wage types from an external subsystem
Description
When external wage types are transferred to the SAP System, costs incurred by the employee in the canteen or for services (such as at a gas station) can be processed by the payroll accounting program as a net deduction.
The data is entered in an external subsystem and uploaded into the SAP System using the standard R/3 communication module. In the certified interface, time event type P50 is reserved for transferring external wage types using the communications channel KK1. The conversion of external wage types into internal SAP wage types is determined in the customizing system and written to the subsystem via a download procedure for validation purposes.
Integration with the payroll accounting program is effected via a batch input program that converts the external wage types into internal wage types and stores the resulting data as a batch input session for the infotypes Employee Remuneration Information and Additional Payments.
The batch input session can be downloaded, uploaded, posted, created, and processed in the background. If errors occur within this process chain, they are displayed in the time management work list where they can be solved.
