Export to excel problem

Hi All,

I am getting some problem, when I am Implementing the excel eport functionality from webdynpro.

The data is exporting to excel properly but the problem is , when i am opening that excel sheet it is asking for the three options like 1) open this file as an XML list, 2)As read only work book, 3)use xml source task pane.

I dont know why it is asking for those options, when I am opening that excel sheet.

My requirement is, it should open as if we open normal excel sheet.

What could be the problem?

Any ideas.

Regards,

Bala
