Refreshing a cube file, which recreates it with the most recent data from the server cube, can be time consuming and require a lot of temporary disk space. Start the process at a time when you do not need immediate access to other files, and make sure you have adequate disk space to resave the file.
To cancel a refresh in progress, press ESC.
Note When you work with OLAP data offline, do not put the .cub file in the Windows briefcase. Excel does not use the briefcase to synchronize the offline cube file with the server database.
