Some sections in your report may not have data but the header sections might print. In these cases to make it informative for the user a “No data available” message might be helpful since the user is then assured that there is no data for that particular data section. This tip will guide you on how to setup “No data available”.
Select the Tablix/List/Matrix control where you want the message to be available and open the properties window, Find the property “NoRowsMessage”. This property can be filled in with text or for dynamic text using expressions. Type in something like “No data available”
When there is no data for that particular section SSRS automatically prints the text under “NoRowsMessage”
