Function Modules in HR

Function modules are program modules which have a defined interface and allow type testing of parameters.

They are managed with transaction SE37 and combined to function groups according to relevant criteria. You can access this transaction under Start of the navigation path Tools Next navigation step ABAP Workbench Next navigation step Function Builder End of the navigation path .

The HR function groups use the naming convention RPxx or HRxx where xx is an identifier of your choice.

You can use the SHOW FUNCTION * editor command to branch from report processing to function module display.
