You created a key figure and want to add calculations.

Key figure calculations in SAP IBP, configured in the Planning Areas app, follow specific rules, per SAP IBP’s calculation engine documentation.

Option A: All key figure calculations have calculation inputs, which can be marked as stored or calculatedThis is correct. Calculations (e.g., KF3 = KF1 + KF2) use inputs that are either stored (persisted data) or calculated (derived), a fundamental rule, per SAP IBP’s guides.

Option B: The calculation chain for a key figure must always result in a calculated key figureThis is incorrect. The chain can result in a stored key figure if configured to persist, notalways calculated.

Option C: Aggregation calculations using SUM or MAX functions must be based on a higher aggregation levelThis is incorrect. Aggregation can occur at any level, not strictly higher; it depends on the planning level definition.

Option D: Key figures can be calculated across the different planning levelsThis is correct. Calculations can span levels (e.g., aggregating from PERPROD to PERPRODLOC), using disaggregation/aggregation, per SAP IBP’s flexibility.

Thus, A and D are key rules, per SAP IBP’s official calculation principles.
