[MSS On Employee Behalf of] Get PERNR of Employee from a custom feeder class

Hi Experts,

Recently someone here assisted me on suggesting to use the MSS On Employee Behalf of functionality to perform certain actions for your employee so thanks for that.

However I have some future developments that will require my custom Webdynpro Application and custom Feeder Class to be used for this feature.

Question is how can I get the PERNR of the Employee the manager is processing? Example if the managers PERNR = 50 and the Employee = 100, the Feeder Class should pick up the PERNR = 100 (which belongs to the employee).

Currently in the IF_FPM_GUIBB_FORM~GET_DATA method of the feeder class I am using the line of Code

g_pernr = cl_hress_employee_services=>get_instance( )->get_pernr( ).

however this only gets the PERNR of the manager. Is there a way to get the PERNR of the employee?

Hope to hear from you all soon.

Regards
