Deleting the InfoCube and InfoCube Content 
Deleting the InfoCube
The whole InfoCube in its definition with all the data is deleted using this function. Dependent objects such as queries and update rules can be deleted with this if desired.
Note that this function results in the irrevocable loss of all data and definitions for the InfoCube.

InfoObjects that have been transferred to the InfoCube cannot be removed from the InfoCube once it has been activated. The only exception here is the state of an InfoCube directly after the function "Delete InfoCube Data" is executed, since all data base tables are in their initial state following this function, that is, they do not contain any data.
This same is true when assigning characteristics to dimensions. This assignment can only be reversed again after the deletion.
