Special characters downloading file into application server

Question

Dear Friends,
i have to download records into excel sheet through back ground job, while downloading records into applications server.
all records are downloading properly up to here fine but some special characters also downloading. i had downloaded same records in debugging mode from the same internal table here no special characters.
i found that the structure(standard ( /SCWM/S_LIME_ALL_MON )) which is being used in that some fields are defined as RAW data type this may be the problem.but i tried to convert them using some function modules no result getting dump only.
i am using data sets to download data into application server here gui_download will not work because it is back ground job.
can any one please help me in this. its urgent...
please please help me in this it has been pending since DEC-01-11.
extra characters like (  #v#M?LQia#####
#v#M?LQia#####
#v#)
my code
  open DATASET LV_FLNAM for OUTPUT in LEGACY BINARY MODE .
  IF sy-subrc EQ C_ZERO.
    LOOP AT LT_TAB INTO WA_TAB.
      transfer WA_TAB to LV_FLNAM.
    ENDLOOP.
    CLOSE DATASET LV_FLNAM.
  ENDIF.

i have to download what are the fields defined as structure.
1)when ever i am using the internal table(LT_TAB) to download getting specials characters(####) with all records for the fields QUAN, QUANA, WEGHT,VOLUM and CAPA.
open DATASET LV_FLNAM for OUTPUT in LEGACY BINARY MODE .
IF sy-subrc EQ C_ZERO.
  CLEAR: WA_stru,
         wa_tab.
  LOOP AT LT_TAB INTO WA_TAB.
    transfer WA_TAB to LV_FLNAM.
    CLEAR: WA_TAB.
  ENDLOOP.
  CLOSE DATASET LV_FLNAM.
ENDIF.
2)if i take another internal table with converting them as char file is downloading with out special characters but it is downloading single line only but not the hole data.
if i have the below code getting only single line records not total records without special characters.
open DATASET LV_FLNAM for OUTPUT in LEGACY BINARY MODE .
IF sy-subrc EQ C_ZERO.
  CLEAR: WA_stru,
         wa_tab.
  LOOP AT LT_TAB INTO WA_TAB.
     wa_stru-LGTYP = wa_tab-LGTYP.
     wa_stru-LGPLA = wa_tab-LGPLA.
     wa_stru-MATNR = wa_tab-MATNR.
     wa_stru-MAKTX = wa_tab-MAKTX.
     wa_stru-QUAN = wa_tab-QUAN.
     wa_stru-UNIT = wa_tab-UNIT.
     wa_stru-CAT = wa_tab-CAT.
     wa_stru-CAT_TXT = wa_tab-CAT_TXT.
     wa_stru-CHARG = wa_tab-CHARG.
     wa_stru-OWNER = wa_tab-OWNER.
     wa_stru-ENTITLED = wa_tab-ENTITLED.
     wa_stru-UI_WDATT = wa_tab-UI_WDATT.
     wa_stru-UI_WDATU = wa_tab-UI_WDATU.     
     wa_stru-SKZSI = wa_tab-SKZSI.
     wa_stru-QUANA = wa_tab-QUANA.
     wa_stru-ALTME = wa_tab-ALTME.
     wa_stru-ITMNO = wa_tab-ITMNO.
     wa_stru-WEIGHT = wa_tab-WEIGHT.
     wa_stru-UNIT_W = wa_tab-UNIT_W.
     wa_stru-VOLUM = wa_tab-VOLUM.
     wa_stru-UNIT_V = wa_tab-UNIT_V.
