• What is the cause and solution for SAP error message MA189 - Historical periods lie outside the planning horizon ?

  The SAP error message MA189, which states "Historical periods lie outside the planning horizon," typically occurs in the context of Material Requirements Planning (MRP) or when working with planning data in SAP. This error indicates that the system is trying to access historical data that is not within the defined planning horizon for the material or product in question.
  Cause:
  
  Planning Horizon Configuration: The planning horizon is set in the material master or in the planning parameters, and it defines the time frame for which planning is performed. If historical data (e.g., sales orders, forecasts) falls outside this defined horizon, the error will occur.
  Data Availability: The historical data that the system is trying to access may not be available or may have been archived or deleted.
  Incorrect Settings: The settings in the material master or the planning strategy may not align with the actual data available, leading to discrepancies.
  
  Solution:
  
  
  Check Planning Horizon Settings:
  
  Go to the material master (transaction code MM03) and check the MRP views. Ensure that the planning horizon is set correctly and encompasses the historical data you need.
  You can also check the planning parameters in the MRP settings (transaction code OMD0) to ensure they are configured correctly.
  
  
  
  Adjust Historical Data:
  
  If the historical data is indeed outside the planning horizon, consider extending the planning horizon to include the necessary historical periods.
  Alternatively, if the historical data is not needed, you may need to adjust your planning strategy or data requirements.
  
  
  
  Review Data Availability:
  
  Ensure that the historical data you are trying to access is available in the system. Check if any data archiving has occurred that might have removed the necessary records.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific details on how to configure planning horizons and manage historical data.
  
  
  
  Testing:
  
  After making changes, run the planning process again to see if the error persists. If it does, further investigation into the specific material and its settings may be required.
  
  
  
  Related Information:
  
  Transaction Codes: MM03 (Display Material), OMD0 (MRP Parameters), MD01 (MRP Run).
  MRP Views: Understanding the MRP views in the material master is crucial for effective planning.
  Planning Strategies: Familiarize yourself with different planning strategies (e.g., Make-to-Stock, Make-to-Order) as they can affect how historical data is utilized.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
