  The SAP error message /SAPAPO/PR461 indicates that there are not enough values available for the median method in the context of demand planning or forecasting within SAP Advanced Planning and Optimization (APO). This error typically arises when the system attempts to calculate a median forecast but does not have sufficient historical data points to perform the calculation.
  Cause:
