@markjw - I am glad you are around this is driving me insane. Yes clicking on the link does nothing, and in your image there is a bottom message “Click on one of these links to Export Data” - I do not have that?
Q said he was to create an interface “Now I’ll create an interface on report explorer and related action” - so how do you do that?
Creating the Export template made them automatically appear on the REPORTS Menu?
Here is your link - notice the very last line in the image: Bottom Left.
