Correct abap code - selectinf file by routine

Question

Hi All,
Please correct my ABAP. I am selecting file by writing routine - BI7.0.
Following error I am getting:
When I clicked preview data i got "Fine Name wrong."
My file name. : 10042007.csv
Following code I wrote:
*TABLES: ...
DATA: str1(60) TYPE c,
str2(10) TYPE c,
str3(10) TYPE c.
str1 = 'C:\Documents and Settings\sun\Desktop/'.
str2 = SY-DATUM.
str3 = 'csv'.
$$ end of global - insert your declaration only before this line   -
form compute_flat_file_filename
  using    p_infopackage  type rslogdpid
           p_datasource   type rsoltpsourcer
           p_logsys       type rsslogsys
  changing p_filename     type RSFILENM
           p_subrc        like sy-subrc.
$$ begin of routine - insert your code only below this line        -
This routine will be called by the adapter,
when the infopackage is executed.
concatenate str1 '\' str2 '.' str3 into p_filename.
          p_subrc = 0.
When I click check button its giving me No systax error.
Thanks in advance

1. if i were you, i will debugg your flat file determination code. put unconditional loop in your code (which should not end any more).
go to SM51, debugg the process from menu options.
or
try to keep file name without spaces i.e. Documents_settings like that.
Hope this helps.
