Other advantages of virtual cubes

The use of virtual cubes in your solution may also simplify the development of some TM1 active reports and websheets by centralizing information into a single location. In fact, some active reports may not be possible without the use of a virtual cube.

For other software, your organization may use TM1 cubes as a reporting source and may require all data to be located in a single cube. Of course, the performance must be evaluated and may require that you use a standard TM1 cube loaded with static data in some cases.
