We’re using OLAP for reports and we got a dynamic datasource, but some times this datasource is empty and we got the error message. There’s any event that we can handle on empty datasource to show a custom message?
Thank you for requesting. You should be sure that CORS is enabled and for that purpose you can use this site. http://enable-cors.org/
Still if you change CORS and this file exists, so this message automatically disappear respectively.
