How to get some character as a field separator while in GUI_DOWNLOAD ?

Question

Hi Friends,
I have to download data from an internal table to a text file. The field separator
between the fields should be comms (,). So, after getting the data into internal table i'm calling the Function Module GUI_DOWNLOAD. Now using this function module can i insert a comma spearator between the fields, if not what is the other way to do it?

Hi,
Its not possible to give the field separator as ',' directly with gui_download from you internal table.
Below is the example through which you can achieve the following,
this is a tested program and is working fine on the system....
so you can use the logic to achieve the following result.... hope this logic helps you to achieve your functionality....
DATA:
BEGIN OF fs,
   col1(6) TYPE c,
   col2(4) TYPE c,
   col3 TYPE c,
   END OF fs.
DATA :
BEGIN OF line,
line(255) TYPE c,
END OF line.
DATA: itab LIKE TABLE OF fs,
      itab2 LIKE TABLE OF line.
DEFINE m_tab.
  clear fs.
  fs-col1 = &1.
  fs-col2 = &2.
  fs-col3 = &3.
  append fs to itab.
END-OF-DEFINITION.
m_tab '006000' '0010' 'J'.
m_tab '006000' '0010' 'J'.
m_tab '006000' '0010' 'M'.
m_tab '006000' '0010' 'M'.
m_tab '006000' '0010' 'O'.
m_tab '006000' '0010' 'O'.
m_tab '006000' '0010' 'T'.
m_tab '006000' '0010' 'T'.
LOOP AT itab INTO fs.
  CONCATENATE fs-col1
              fs-col2
              fs-col3
         INTO line
SEPARATED BY ','.
  APPEND line TO itab2.
ENDLOOP.
