Open a PDF file located in a network folder in WD ABAP application

Hello,

I need to open a PDF file in my Web Dynpro ABAP application:

1) The PDF file is located in a shared folder (e.g.
host\files\file.pdf)

2) If I build an ALV table in my application and create a linktourl element that opens the following path "file://host/files/file.pdf" I have success

3) Now, instead of having the linktourl element in my table I want to have a button that saves the pdf located in
host\files\file.pdf to the user's local PC and then opens the PDF

Do you know if this is possible?

Can you explain me how to do it?

Thanks in advance.

Kind regards,

Ricardo
