• What is the cause and solution for SAP error message EL420 - &1: Overflow dev. &2, reg. &3; MR results from &4 higher than inspection ?

  The SAP error message EL420 indicates an overflow condition in the context of a measurement result (MR) that exceeds the expected limits during a quality inspection process. This error typically arises in the context of Quality Management (QM) within SAP, particularly when dealing with inspection lots and measurement documents.
  Cause:
  
  Measurement Result Exceeds Limits: The error occurs when the measurement result recorded for a characteristic exceeds the defined upper limit or threshold for that characteristic in the inspection plan.
  Data Type Limitations: The data type used for storing measurement results may have a limited range, leading to overflow if the value exceeds this range.
  Incorrect Configuration: The inspection characteristics may not be configured correctly, leading to unrealistic expectations for measurement results.
  Unit of Measure Issues: There may be discrepancies in the unit of measure used for the measurement results compared to what is defined in the inspection plan.
  
  Solution:
  
  Check Measurement Results: Review the measurement results entered for the inspection lot. Ensure that they are within the defined limits set in the inspection plan.
  Inspect Inspection Plan: Verify the inspection plan settings for the characteristic in question. Check the upper and lower limits defined for the measurement.
  Adjust Data Types: If the measurement results are valid but exceed the limits due to data type constraints, consider adjusting the data type or the field length in the configuration.
  Review Units of Measure: Ensure that the units of measure used for the measurement results are consistent with those defined in the inspection plan.
  Correct Configuration: If the inspection characteristics are incorrectly configured, update the configuration to reflect the correct limits and data types.
