What causes this issue?

An InfoCube, that has already been activated and contains data, must

new dimensions may be defined,
InfoObjects for existing dimensions may be written to it.
You may not, however,
change the InfoCube type
remove InfoObjects,
change the assignment of InfoObjects to dimensions
and so on.
