How to apply WWW_LIST_TO_HTML - Open/Transfer/Close Dataset to ALV Reports

Question

hello people! So far I have done some good progress regarding this thanks to many of you people. I do have some hurdles and one of them involves ALV Reports. So far I use
WWW_LIST_TO_HTML - to temporarly store the list report to a table known as ihtml.
and Open/Transfer/Close data set to send the file to the application server using the syntax below
<b>OPEN DATASET file FOR OUTPUT IN BINARY MODE.
LOOP AT ihtml.
  TRANSFER ihtml TO file.
ENDLOOP.
CLOSE DATASET file.</b>
So far the program works fine in the report with the expection if its one that generates an ALV Report.
My question is that is there a way to successfully run the program the way it was mentioned above using ALV? If so what techniques do you guys suggest?
<b>Note:</b> Also please note the report and transfering/writing of the file has to be done during background processing.
Hope I get some replies soon as many of you have been most helpful thank you and good day.

Hi chad,
1. yes u are right
2. it will give this error only.
3. the reason is, the www_list_to_html
   is exected after list display,
4. the code comes there when
   we press BACK, and at that time
   no list is there in memory.
<b>5. So we have to use some workaround.
6. END_OF_LIST
7. We have to use this EVENT
   and inside this event,
   we have to export to HTML.</b>
8. I tried and it works FANTASTIC
9. Just copy paste this program.
      (it will show a alv list of t001,
    and write the HTML file also)
  ( i have used END_OF_LIST event)
