Handle xls file generated in ECC which is in different format

Hi Experts,

ABAP code generates a file a post it in an shared folder and PI should pick it up but after PI pushes the file to receiver and when tries to open it throws a warning as shown below:

But when I manually try to save the file as "Microsoft Excel 97-2003 Worksheet (.xls)", I could open the file with out warning. Can we avoid the manual intervention by here to avoid the warning?

Thanks,

Naveen.
