Submit + LIST_FROM_MEMORY in background mode

Question

Hi,
I need to capture the output results from standard program RFKORK00 and hence I designed a wrapper program that calls the standard program.
RFKORK00 generates a report output and I am able to capture the results correctly using the FM LIST_FROM_MEMORY and FM LIST_FROM_ASCI in foreground mode. But when I try to run the same job in background, the FM LIST_FROM_MEMORY does not return any results (I have checked the log by inserting information messages at various points in the program).
I have searched for similar contexts here on SDN and everyone is in agreement that LIST_FROM_MEMORY would work well even in the background mode too but I am unable to find the fault in this case. Could you please help, attached is the code -
SUBMIT RFKORK00
      USING SELECTION-SET c_variant
      EXPORTING LIST TO MEMORY
      AND RETURN.
    CALL FUNCTION 'LIST_FROM_MEMORY'
      TABLES
        listobject = lt_abaplist
      EXCEPTIONS
        not_found  = 1
        OTHERS     = 2.
    IF sy-subrc = 0.
      CALL FUNCTION 'LIST_TO_ASCI'
        EXPORTING
          list_index         = '-1'
          with_line_break    = ' '
        TABLES
          listasci           = lt_vlist[]
          listobject         = lt_abaplist[]
        EXCEPTIONS
          empty_list         = 1
          list_index_invalid = 2
          OTHERS             = 3.
      IF sy-subrc <> 0.
        MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
      ENDIF.
      MESSAGE i099(z1) WITH 'LIST TO ASCI CALL'.
   ENDIF.

Well, RFKORK00 is indeed a print program that triggers spool in the background.
I gave up playing around memory id, instead I am using the following code to check whether a spool was created in table TSP03.
CLEAR r_rqcretime[].
    r_rqcretime-sign    = 'I'.
    r_rqcretime-option  = 'BT'.
    CALL FUNCTION 'IB_CONVERT_INTO_TIMESTAMP'
      EXPORTING
        i_datlo     = sy-datlo
        i_timlo     = sy-uzeit
        i_tzone     = 'EST'
      IMPORTING
        e_timestamp = v_tzntstmps.
    r_rqcretime-low = v_tzntstmps.
**Submit job with changed variant
    SUBMIT (p_prog)
      USING SELECTION-SET c_variant
      EXPORTING LIST TO MEMORY
      AND RETURN.
    WAIT UP TO 5 SECONDS.
**Fetch the spool number generated by the program
    CALL FUNCTION 'IB_CONVERT_INTO_TIMESTAMP'
      EXPORTING
        i_datlo     = sy-datlo
        i_timlo     = sy-uzeit
        i_tzone     = 'EST'
      IMPORTING
        e_timestamp = v_tzntstmps.
    r_rqcretime-high = v_tzntstmps.
    CONDENSE: r_rqcretime-low,r_rqcretime-high.
    CONCATENATE r_rqcretime-low   '00' INTO r_rqcretime-low.
    CONCATENATE r_rqcretime-high  '00' INTO r_rqcretime-high.
    APPEND r_rqcretime.
    SELECT SINGLE rqident FROM tsp01
                  INTO v_rqident
                 WHERE rqowner = sy-uname
                   AND rqcretime IN r_rqcretime.
