Transfer Wage Types with Split Indicator (T558B)
Transfer External Payroll-Arrears Results – International (T558E)
For performance reasons, these tables are only updated once per input file.
Before the data is transferred to the tables, the system deletes the existing entries for the respective personnel numbers. The Start date (BEGDA) and End date (ENDDA) fields are filled with the end date of the current payroll period.
To create an example for an input file, you can use report RPUOUTIDOC. This report creates IDocs from the entries in tables T558B, T558D, and T558I. You can write to a file interface using the IDoc exit.
