    I_TITLE                       = 'SALES ORDER INFO'
    I_ZEBRA                       = 'X'
    I_TABNAME                     = 1
    I_STRUCTURE_NAME              = 'VBAK'
  TABLES
    T_OUTTAB                      = it_vbak
   EXCEPTIONS
     PROGRAM_ERROR                 = 1
     OTHERS                        = 2.

The following code may be of some help:
DATA: BEGIN OF it_prmhlp OCCURS 0.
        INCLUDE STRUCTURE zaltab_param.
DATA: flg(1) TYPE c,
      END OF it_prmhlp.
  DATA: wreturn LIKE ddshretval OCCURS 0 WITH HEADER LINE,
    wstep LIKE sy-stepl.
  DATA wsel1 VALUE 'X'. wsel1 = 'X'.
  TYPE-POOLS : slis.
  DATA : listtitle(30),
         l_lines     LIKE sy-tabix,
         ls_fldcat   TYPE slis_fieldcat_alv,
         lt_fldcat   TYPE slis_t_fieldcat_alv,
         ls_selfield TYPE slis_selfield.
  progname = sy-repid.
  dynnum   = sy-dynnr.
  DEFINE fldcat_add1.
    ls_fldcat-fieldname     = &1.
    ls_fldcat-ref_tabname   = &2.
    ls_fldcat-ref_fieldname = &3.
    ls_fldcat-reptext_ddic  = &4.
    ls_fldcat-outputlen     = &5.
    append ls_fldcat to lt_fldcat.
  END-OF-DEFINITION.
  REFRESH : lt_fldcat.
  fldcat_add1 'AUREL' 'ZALTAB_PARAM' 'AUREL' 'Alloc Table Relevancy' '25'.
  fldcat_add1 'PDESC' 'ZALTAB_PARAM' 'PDESC' 'Process Description' '40'.
  REFRESH it_prmhlp. CLEAR it_prmhlp.
  SELECT * FROM zaltab_param
    INTO TABLE it_prmhlp
    WHERE tcode = sy-tcode.
  SORT it_prmhlp BY aurel pdesc.
  listtitle = 'Allocaction Table Relvancy Selection'.
  CALL FUNCTION 'REUSE_ALV_POPUP_TO_SELECT'
       EXPORTING
            i_title                 = listtitle
            i_selection             = wsel1
            i_zebra                 = ' '
            i_checkbox_fieldname    = 'FLG'
            i_tabname               = 'IT_PRMHLP'
            it_fieldcat             = lt_fldcat
       TABLES
            t_outtab                = it_prmhlp
       EXCEPTIONS
            program_error           = 1
            OTHERS                  = 2
  DATA wfl1. CLEAR wfl1.
  LOOP AT it_prmhlp.
    IF it_prmhlp-flg = 'X'.
      IF wfl1 = 'X'.
        CLEAR it_prmhlp. REFRESH it_prmhlp.
        MESSAGE i000(yw) WITH 'Only 1 entry can be selected...'.
        EXIT.
      ENDIF.
      wfl1 = 'X'.
    ENDIF.
  ENDLOOP.
  IF wsel1 = 'X'.
    READ TABLE it_prmhlp WITH KEY flg = 'X'.
    IF sy-subrc EQ 0.
      paurel = it_prmhlp-aurel.
      paureltx = it_prmhlp-pdesc.
      wvariant = it_prmhlp-zvariant.
      PERFORM update_screen.
    ELSE.
      CLEAR it_prmhlp. REFRESH it_prmhlp.
    ENDIF.
  ENDIF.
The trick lies in using the box fieldname which is 'FLG' in this case and the wsel1 param passed to the fm to know whether any row is selected or not.
