Display help for a field. Useful for doing AT SELECTION SCREEN ON VALUE REQUEST for those fields that do not provide F4 help at the DDIC level.


 CALL FUNCTION 'HELP_START'
       EXPORTING
            HELP_INFOS   = LSTR_HELP_INFO
       IMPORTING
            SELECTION    = LC_SELECTION
            SELECT_VALUE = LC_SELECTION_VALUE
       TABLES
            DYNPSELECT   = FTAB_DYNPSELECT
            DYNPVALUETAB = FTAB_DYNPVALUETAB
       EXCEPTIONS
            OTHERS       = 1.

  IF LC_SELECTION NE SPACE AND SY-SUBRC = 0.
    F_NEWVALUE = LC_SELECTION_VALUE.
  ENDIF.

In the Debugger, check the CALLS tab, you will find how the FM HELP_START is being called?

Start the System debugging (System > Utilities > Debug System ) and check the CALLS.
