While creating a planning view in SAP IBP, what parameter is not adjustable by the user?

When creating a planning view in SAP IBP, the parameter that is not adjustable by the user is capacity allocation parameters. This is because these parameters are typically set at a higher level within the system and are influenced by overarching business rules and configurations established by the system administrators or during the implementation of IBP. As such, they are consistent across various planning views and are intended to ensure a unified approach to capacity management.

On the other hand, default values for time profiles, global planning horizons, and time zone settings are generally more flexible for users to adjust according to specific needs within their planning activities. Users have the ability to define and modify these elements to fit unique scenarios or requirements within their organization, allowing for tailored planning processes without affecting the underlying capacity parameters that govern resource management across the board.
