[ALV] Save as dialog box is - in fact - Save as Web Page

Hi,

When exporting ALV to Excel from a Web Dynpro application, the Excel file opens correctly.

But, upon calling the "Save as" entry, the dialog box is not the expected one: it is the Save as Web page one.

Although I tried to change Excel format using the standard report SALV_BS_ADMIN_MAINTAIN, I didn't succeed in changing this.

Could someone point me on a customizing point I missed or a resource by Microsoft dealing with this aspect?

Many thanks in advance.

Best regards,

Guillaume
