Read Excel File in SAP PI

Hi All,

I am working on a requirement of picking a excel (xsl or xlsx) file from shared location in SAP ECC and send it to some other location at target side with out any transformation.

I have read many blogs and could required information for developing .

https://blogs.sap.com/2014/09/25/a-simple-approach-in-reading-excel-file/

But still need some more information and so I am posting here . So my doubt is " Do I have to create ESR objects for this " if so why do i need to create. This doubt comes to be becz it is only processing file from one location to other location only then why ESR objects.

If I have to create ESR objects will that be based on Excel file data fields.

Appreciate your valuable inputs.

Thankyou
