Maximum number of D-Cubes in a single application

Cognos Planning applications have a limit of 10 D-Cubes per application. D-Cubes are the multidimensional structures that hold data and calculations, and this architectural limit prevents excessively complex models that would impact performance and maintainability. The limit forces planners to design efficiently, potentially splitting very large models across multiple applications if more than 10 cubes are truly needed.
