• What is the cause and solution for SAP error message W4405 - &: & forecast messages with MRP areas were deleted ?

  Certainly! Here's a detailed explanation regarding the SAP error message:
  
  SAP Message:
  W4405: & forecast messages with MRP areas were deleted
  
  Meaning / Cause:
  
  This warning message indicates that forecast data (planning data) that was assigned to specific MRP areas has been deleted during an MRP run or forecast update.
  MRP areas are organizational units within SAP that allow material requirements planning to be performed for specific areas (e.g., plants, storage locations, production lines).
  The deletion of forecast messages with MRP areas usually happens when:
  
  The forecast data is outdated or no longer valid.
  The forecast was manually or automatically deleted due to changes in planning parameters.
  The MRP run or forecast update process cleans up old or irrelevant forecast data.
  There is a mismatch or inconsistency in the forecast data related to MRP areas.
  
  
  
  
  When does it occur?
  
  During forecast update (transaction like MP30, MP31, or during MRP run).
  When forecast data is maintained or deleted for materials with MRP areas.
  When forecast data is transferred or adjusted and the system removes obsolete forecast messages.
  
  
  Impact:
  
  This is a warning message (W), not an error, so the MRP run or forecast update usually continues.
  It informs the planner or user that some forecast data related to MRP areas has been deleted.
  If forecast data is critical for planning, its deletion might affect planning results or stock requirements.
  
  
  Solution / Actions:
  
  
  Check Forecast Data:
  
  Review the forecast data for the material and MRP area in question.
  Use transaction MP30 (Forecast) or MD61/MD62 (Demand Management) to check forecast entries.
  Verify if the forecast data is still relevant or if it was intentionally deleted.
  
  
  
  Review MRP Area Settings:
  
  Check the configuration of MRP areas in SPRO under:
  Logistics - General > Material Requirements Planning > Master Data > MRP Areas > Define MRP Areas
  Ensure that MRP areas are correctly assigned and active.
  
  
  
  Check MRP Parameters:
  
  Verify if the MRP type, lot size, and forecast parameters are consistent.
  Sometimes, changes in MRP parameters can cause forecast data to be deleted.
  
  
  
  Recreate Forecast if Needed:
  
  If forecast data was deleted unintentionally, recreate or re-import forecast data.
  Use transaction MP30 or upload forecast data again.
  
  
  
  Check for Custom Code or User Exits:
  
  Sometimes custom programs or user exits might delete forecast data.
  Review any custom logic that might affect forecast messages with MRP areas.
  
  
  
  Monitor MRP Logs:
  
  Check MRP run logs (MD04, MD05, MD06) for additional messages or clues.
  Look for related messages that might explain why forecast data was deleted.
  
  
  
  
  Related Information:
