• What is the cause and solution for SAP error message W4402 - &: & Forecast parameters with MRP area were deleted ?

  SAP Error Message:
  W4402: "& Forecast parameters with MRP area were deleted"
  
  
  Cause:
  This warning message occurs when forecast parameters that are assigned to a specific MRP area have been deleted. In SAP, forecast parameters define how the system calculates forecasts for materials, and these parameters can be maintained at the plant level or at the MRP area level (subdivision of a plant for planning purposes).
  If forecast parameters for an MRP area are deleted (either intentionally or accidentally), but the system or planning run still references these parameters, SAP issues this warning to indicate that the forecast parameters for that MRP area no longer exist.
  
  Explanation:
  
  Forecast parameters are maintained in transaction MP30 (Maintain Forecast Parameters).
  When forecast parameters are deleted for an MRP area, any dependent planning or forecasting processes that expect these parameters will trigger this warning.
  This message is informational/warning (W message), not an error (E message), so it does not stop processing but
