• What is the cause and solution for SAP error message MA657 - Historical horizon shortened due to technical period & ?

  The SAP error message MA657, which states "Historical horizon shortened due to technical period," typically occurs in the context of Material Requirements Planning (MRP) or when dealing with historical data in SAP. This message indicates that the system has limited the historical data available for planning purposes due to the defined technical periods in the system settings.
  Cause:
  
  Technical Period Settings: The error is often caused by the configuration of the technical periods in the MRP settings. If the technical period is set to a value that restricts the historical data available for planning, the system will shorten the historical horizon.
  Data Availability: If there is insufficient historical data available for the material in question, the system may not be able to retrieve the necessary data for planning.
  Master Data Configuration: Issues with the material master data or planning parameters can also lead to this error.
  
  Solution:
  
  
  Check Technical Period Settings:
  
  Navigate to the MRP settings in the SAP system (Transaction code: OMDU or similar).
  Review the configuration of the technical periods and adjust them if necessary to allow for a longer historical horizon.
  
  
  
  Review Material Master Data:
  
  Ensure that the material master data is correctly maintained, including the planning parameters and historical data settings.
  Check if the material has sufficient historical data available for the planning horizon.
  
  
  
  Adjust Planning Parameters:
  
  In the MRP view of the material master, check the planning parameters such as the "Planning Horizon" and "Historical Data" settings.
  Adjust these parameters to ensure that the system can access the required historical data.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on MRP settings and historical data management.
  
  
  
  Testing:
  
  After making changes, run a test MRP run to verify that the error has been resolved and that the historical horizon is now correctly set.
