Be sure the pdf has the correct permissions. A scheduled report has permissions different from the dashboard.
Well, yes, I dont see "permisssion" option in the dashboard for me. So how can the pdf scheduler can be made viewed to other users? they are unable to see the pdf scheduled for that dashboard whereas I can see that.
Under Reports, find the report you are using for the dashboard. Click the Edit drop down, then Edit Permissions. Be sure to set the Read to Everyone, or whatever role system you might be using.
Same issue for me and the dashboard contains inline queries only and permissions are set properly still other member not able to see if the dashboard is set to PDF delivery.
