How can I download from R/3 to flat file?

Question

Hi
My requirement is to download Material and Supplier data from R/3 to flat file...
These are the fields I have to bring it from SAP R/3 but I don not want to DOWNLOAD FM. I want to Concatenate from Internal Table and put it on application server.
There are my following fields...
Material and Supplier
   1. Selection criteria
         - Based on plant
         - Hubs and FSL/Hubs
         - Hubs can pull both Repair and NewBuy vendor
         - FSL/Hubs pull only Repair vendor
   2. Material – EORD-MATNR
   3. Region – Determined by 9* plants
   4. Site
         1. plant-(W) and plant-(C) for FSL/Hubs
         2. plant-(S) for DCs
   5. Supplier
         1. Menlo/Repair for DC
         2. Repair only for hub/fsl
   6. Supplier-type – PURCHASE or REPAIR
   7. Leadtime - (The number of days between placing an order and receiving an order)
   8. Order Horizon – “2”
   9. Minimum OQ – “3”
  10. Order cost – “50”
  11. Supplier part number – EORD-MATNR
Waiting for some help and (or) sample code for this...
Thanks in advance.

Here is an example program showing how to write a tab-delimited file to the application server.  All you need to do is get all your data into an internal table, then loop at it, concatenate all fields into a string and then transfer that string.
report zrich_0001.
parameters: d1 type localfile default '/usr/sap/TST/SYS/Test.txt'.
data: begin of itab occurs 0,
      field1(20) type c,
      field2(20) type c,
      field3(20) type c,
      end of itab.
data: str type string.
constants: con_tab type x value '09'.
* if you have a newer version, then you can use this instead.
*constants:
*    con_tab  type c value cl_abap_char_utilities=>HORIZONTAL_TAB.
start-of-selection.
itab-field1 = 'ABC'.
itab-field2 = 'DEF'.
itab-field3 = 'GHI'.
append itab.
itab-field1 = '123'.
itab-field2 = '456'.
itab-field3 = '789'.
append itab.
  open dataset d1 for output in text mode.
  loop at itab.
    concatenate itab-field1 itab-field2 itab-field2 into str
                  separated by con_tab.
    transfer str to d1.
  endloop.
  close dataset d1.
