When configuring a complex calculation using helper key figures, which consideration is important?

Using helper key figures in complex calculations allows for flexibility and efficiency in SAP Integrated Business Planning (IBP). The correct answer emphasizes that a helper key figure can be utilized across different planning levels, which is essential for maintaining consistency and accuracy in your calculations.

When a helper key figure can operate at various planning levels, it enables users to aggregate or distribute data as needed without duplicating efforts or creating unnecessary complexities in the model. This capability supports dynamic calculations that may rely on inputs or data residing at distinct levels, ensuring that the final results reflect the correct relationships and dependencies present in the planning process.

Furthermore, this approach facilitates more sophisticated planning scenarios where different granularity of data might be involved, allowing planners to comprehensively analyze and interpret the data across the broader context of their business objectives. By enabling the use of the same helper key figure across multiple levels, it reduces the need to create multiple key figures for similar functions, streamlining configuration and improving overall system efficiency.
