Answer 1

At first you mast open the job by calling the function 'JOB_OPEN' like below
  CALL FUNCTION 'JOB_OPEN'
    EXPORTING
  DELANFREP              = ' '
  JOBGROUP               = ' '
      JOBNAME              = name
  SDLSTRTDT              = NO_DATE
  SDLSTRTTM              = NO_TIME
  JOBCLASS               =
   IMPORTING
     JOBCOUNT               = number
CHANGING
  RET                    =
   EXCEPTIONS
     CANT_CREATE_JOB        = 1
     INVALID_JOB_DATA       = 2
     JOBNAME_MISSING        = 3
     OTHERS                 = 4.
  IF SY-SUBRC <> 0.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
