When creating a BI report it is automatically given a name/title, for example Report 1. The almost natural thing to do is to select the cell where the title is displayed and type over it. However if you do this it will make the report disappear.

The reason for this is because the title is generated by an MDX expression (MDX is the cube language that reports are written in).

To rename a report properly select the ‘Rename Report’ icon    

Enter your title in the screen that displays

Click Ok.

Alternatively, if creating a report using the ‘New Report’ icon you are able to enter a title when selecting the the connection

Its a basic tip but one that catches out many!!!!
