Creating a Webi Report with excel as automated process

Hi All,

Need your inputs here. I am using SAP BO 4.1 reporting tool. My requirement is to create a Webi report with Excel as source.

The challenging part here is that the whole process should be automated. I have to place an excel file in some shared location and the webi report should pick up that excel file automatically.User can only update the data in the excel and the headers and all will remain same.So when user refreshes the webi report the report should populate automatically the updated data.

Can any one please suggest me how to achieve this.

Thanks in advance.

Thanks
