Reading the Pernr and benefit data from Standard classes in ESS

Recently I came across a requirement to set the begin date of HSA record when an employee enters “HSA contribution changes” application in the Benefits service in EHP5 WD-ABAP application. The requirement is to default the  start date of HSA change to ENDDA +1 of current pay period.

After a little search, I was able to find the Badi PBEN0040, but the problem is we don’t have Pernr, Benefit event data as importing parameters which is required to default the start date. After debugging the benefit application, I found two standard classes which can be used for this purpose.

cl_hress_employee_services and  cl_hress_ben_services. I have used the first one to read the employee no. who is logged in using the below code.

TRY.

           lv_pernr =

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

         CATCH cx_hress.

       ENDTRY.

and for reading the benefit event, the code is

    lo_instance = cl_hress_ben_services=>get_instance( ).

     lv_ben_event = lo_instance->gv_ben_event.

Hope this is useful
