Which of the following is a prerequisite for configuring a planning area successfully?

To configure a planning area successfully in SAP Integrated Business Planning (IBP), it is essential to ensure that at least one calculated key figure is configured. Calculated key figures are vital because they allow for dynamic calculations based on other key figures, providing insightful analytical data necessary for effective planning. The configuration of calculated key figures enables users to drive the decision-making process through accurate and timely information.

Without having at least one calculated key figure set up, the planning area may lack critical information needed for performing forecasts, evaluations, and simulations that are fundamental to the IBP process. This makes the establishment of a calculated key figure a foundational step in configuring a planning area effectively.

Other options, while potentially relevant to planning area configurations, do not serve as required prerequisites. For instance, having multiple input key figures can aid in data detail but isn't a mandatory condition for the initial configuration. Setting a default time zone can be useful for organizing planning data; however, it's not essential in the fundamental setup of a planning area. Lastly, establishing a maximum limit on planning combinations may affect performance and data storage, but again, it's not an initial prerequisite for configuration. Thus, configuring at least one calculated key figure stands out as a critical requirement.
