• What is the cause and solution for SAP error message FRMLDLG139 - Best practical output is not within the lot size range ?

  The SAP error message FRMLDLG139, which states "Best practical output is not within the lot size range," typically occurs in the context of production planning and control, particularly when dealing with production orders or process orders in SAP.
  Cause:
  This error message indicates that the calculated best practical output for a production process does not fall within the defined lot size range for that particular material or production order. The lot size range is defined in the material master or in the production order settings, and it specifies the minimum and maximum quantities that can be produced in a single production run.
  Possible Reasons:
  
  Incorrect Lot Size Configuration: The lot size range defined in the material master may not be appropriate for the production process.
  Best Practical Output Calculation: The system may have calculated a best practical output based on the production parameters that is outside the defined lot size range.
  Changes in Production Parameters: If there have been recent changes in production parameters (like machine efficiency, setup times, etc.), the best practical output may need to be recalculated.
  Material Master Data Issues: There may be inconsistencies or errors in the material master data related to lot sizes.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Lot Size Configuration:
  
  Go to the material master (transaction code MM03) and check the lot size settings for the relevant material.
  Ensure that the lot size range is appropriate for the production process.
  
  
  
  Review Best Practical Output:
  
  Analyze the production parameters and the calculation of the best practical output.
  If necessary, adjust the parameters to ensure that the output falls within the defined lot size range.
  
  
  
  Adjust Production Order Settings:
  
  If you are working with a specific production order, check the order settings to ensure that the lot size is correctly defined.
  
  
  
  Recalculate Best Practical Output:
  
  If changes have been made to production parameters, you may need to recalculate the best practical output. This can often be done through the production planning module.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidance related to your version of SAP and the configuration of your system.
  
  
  
  User Exits or Enhancements:
  
  If the issue persists, consider whether any user exits or enhancements are affecting the calculation of the best practical output.
  
  
  
  Related Information:
  
  Transaction Codes: MM03 (Display Material), CO01 (Create Production Order), CO02 (Change Production Order).
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  Training and Documentation: Ensure that users involved in production planning are trained on the importance of lot size configurations and best practical output calculations.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
