Download Table Information to Excel

[Former Member]

I am trying to download table information that is populated via RFC to my ERP system. I use a custom controller to handle this process.

I followed the "Exporting Context Data into Excel Using the Web Dynpro Binary Cache"

My problem is when I try to execute the download to excel I receive the following error. Any Thoughts?
