A. Cycle length divided by annual performance: This calculation results in the maintenance interval expressed in years, which is not precise enough for scheduling a specific planned date.
B. Cycle length divided by monthly performance: The standard SAP maintenance plan uses annual performance as the primary input for forecasting, not a separate monthly performance figure.
C. Cycle length divided by ((scheduling period) x (cycle modification factor)): The scheduling period and cycle modification factor are used to control how far in advance calls are generated and to adjust cycles, not to calculate the fundamental performance-based interval.
