Problem with creating a new file in the Filter

Question

hi,
i have the following problem.
1) For all requests ending with *.xml (for example requests such as http://www.asdf.com/feeds/myfile.xml ) i have mapped it to a filter
2 ) In the filter i did the following...................
//getting the file name from the url
//create the file if it does not exists..................
chain(request,reponse);
//done
problem is
3) a) For files which iam not creating in filter (i.e files which are already there) the response is proper it is returning a xml file
b) But for files which are not there already , which we are creating in the filter dynamically it is showing a 404 (i.e file not found message)
But if i refresh again in the browser it is getting a valid XML file.......................................
I could not able to figure it out why it is returning 404 error in cases where the file is being created dynamically.................................
Can any one guide me resolving this problem?

Hi pawan
Try this badi :   MB_MIGO_BADI  -
(BAdI in MIGO for External Detail Subscreens)  as the name suggest ,
If you want to add a screen in header level use : Method : PBO_header an code as :
    e_cprog   = 'ZMMPRM0001'.     """ Your screen created
    e_dynnr   = '1000'.                     "Your screen No
    e_heading = 'TEXT ID '(004).    """" Name of the screen to be created .
  ELSE .
    e_cprog   = 'ZMMPRM0001'.
    e_dynnr   = '1000'.                     "External fields: Display
    e_heading = 'TEXT ID '."(004).
or if at item level
u can use methid : PBO_DETAIL
for item level screen creation . and code in the same maaner ..
You can explore the remaning methods as per your requirements .
Hope it helps ..!
