What do Substitution Variables do regarding Parameters before a Cube View is run?

Substitution Variables play a crucial role in the functionality of Parameters within the Cube View. When a Cube View is executed, these variables allow for the dynamic substitution of values, enabling the exchange of specific members in the Point of View (POV). This means that instead of hardcoding values or relying on fixed parameters, Substitution Variables facilitate a more flexible approach that can adapt based on the context or user input.

For instance, if you set a Substitution Variable for a member in the POV, it allows the Cube View to pull in different members or scenarios without needing to recreate or modify the Cube View itself. This enhances the usability of the model by allowing users to interact with the data in a more versatile manner, leading to tailored analysis based on the specific requirements at the time of execution. This dynamic capability is essential for effective reporting and analysis within OneStream’s environment.

The other options do not accurately represent the function of Substitution Variables. They do not define the structure of the Cube View, which is typically predetermined by the user. While these variables may indirectly contribute to performance improvements through better data handling, they do not aggregate data themselves. Additionally, Substitution Variables do not restrict data access; rather, they provide a means of customizing the data
