You'll need to save and upload your workbook as a .twbx (not twb). We won't be able to view the data source if not. Thanks!
Hi Devendra Supe,
You can add a text box with "No Data Message" and send it to back. So when there is no records in your worksheet the text box with the message will be visible to the end user.
Please have a look into the sample workbook in the link mentioned by Mahfooj Khan.
I have done that but its require both text box and Sheet should be floating and it collapse the all design of dashboard.Is there any alternative for the same answer?
