• What is the cause and solution for SAP error message MPE_CM_EFFECTIVITY085 - Relative quantity could not be determined due to round off error ?

  The SAP error message MPE_CM_EFFECTIVITY085, which states "Relative quantity could not be determined due to round off error," typically occurs in the context of production planning and material management when dealing with effective quantities in a production order or a similar process. This error is often related to issues with rounding during calculations of quantities, especially when dealing with fractional quantities or when the system attempts to allocate materials based on certain criteria.
  Causes:
  
  
  Rounding Issues: The error is primarily caused by rounding discrepancies in the calculations of relative quantities. This can happen when the system tries to allocate materials or calculate quantities based on certain parameters, and the resulting value cannot be accurately represented due to rounding.
  
  
  Decimal Places Configuration: If the configuration for decimal places in the material master or in the relevant settings is not aligned with the actual quantities being processed, it can lead to rounding errors.
  
  
  Batch Management: If batch management is enabled and there are issues with batch quantities or allocations, it can also lead to this error.
  
  
  Effective Date Changes: Changes in effective dates or validity periods for certain materials or production orders can lead to discrepancies in quantity calculations.
  
  
  Solutions:
  
  
  Check Decimal Places: Review the configuration for decimal places in the material master and ensure that it is set correctly. Adjust the settings if necessary to allow for more precise calculations.
  
  
  Review Quantity Calculations: Analyze the specific production order or transaction that triggered the error. Check the quantities involved and see if there are any discrepancies or unusual values that could lead to rounding issues.
  
  
  Adjust Rounding Settings: If applicable, adjust the rounding settings in the configuration of the relevant modules (e.g., Material Management, Production Planning) to minimize rounding errors.
  
  
  Batch Management Review: If batch management is in use, ensure that the batch quantities are correctly defined and that there are no conflicts or issues with batch allocations.
  
  
  Reprocess the Transaction: Sometimes, simply reprocessing the transaction after making the necessary adjustments can resolve the issue.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes or patches that may address this specific error message. There may be known issues or updates that can help resolve the problem.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for detailed information on effective quantities, rounding rules, and configuration settings.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Testing: If changes are made to configurations, it is advisable to test in a development or quality assurance environment before applying changes to the production system.
  
  By addressing the underlying causes of the rounding error and ensuring that configurations are set correctly, you can resolve the MPE_CM_EFFECTIVITY085 error and prevent it from occurring in the future.
