Transfer ITAB contents to PDF format

Question

Hi,
I want to transfer ITAB contents to PDF.format. For this iam following above steps:
(Note: my output in Z-report1 is in classical format and year wise but in output it contain all 12 moths data so i want to generate new PDF file for each month separately if i run this report in background then it will generate only one spool request for all 12 months)
1) Z- report through which iam transferring ITAB comtents to memory ID.
2) then through SUBMIT iam calling new Z-report1.
3) then iam importing ITAB content to Z-report1.
4) Now to get the Spool no i want to execute Z-report1 in background (automatically it should run in background because iam calling Z-report1 in Z-report).
SO is there any function module so that i can pass report name (Z-report1) and it will run in background
Please help.
Thanks .
Regards.
Hemant.

You can submit a program via job. Check the F1 help on submit button.
I'm doing something similar :
Here is the code snippet for submitting the program and getting the spool request.
  SUBMIT (gwa_rkb1d-rname) TO SAP-SPOOL COVER TEXT t_stamp
  WITHOUT SPOOL DYNPRO IMMEDIATELY flag KEEP IN SPOOL flag_kisp
  WITH    SELECTION-TABLE seltab   USING SELECTION-SET p_vari
  AND RETURN.
  SELECT SINGLE *
    INTO t_tsp01
    FROM tsp01
    WHERE rqfinal   IN ('.','X')
    AND   rqclient  = sy-mandt
    AND   rqowner   = sy-uname
    AND   rqtitle   = t_stamp.
  IF sy-subrc = 0.
    CALL FUNCTION 'RSPO_RETURN_ABAP_SPOOLJOB'
      EXPORTING
        rqident              = t_tsp01-rqident
      TABLES
        buffer               = buffer
      EXCEPTIONS
        no_such_job          = 1
        not_abap_list        = 2
        job_contains_no_data = 3
        selection_empty      = 4
        no_permission        = 5
        can_not_access       = 6
        read_error           = 7
        OTHERS               = 8.
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
      WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
  ENDIF.
Also Job_open, job_submit and Job_close functions can be used.
