Error in Exporting to Excel 2003 office format in ALV

Hi,

I got an error while attempting to use the export to spreadsheet(in office 2003 XML) format.

It is opening a 'Save As' dialog box instead of exporting the report content to excel.

The option i tried is,

List-->Export-->spreadsheet-->office 2003 XML format

Please provide a solution.

Thanks,

Loganathan Mohanasundaram
