• What is the cause and solution for SAP error message QE300 - Conversion factor for sample UoM & not maintained for charac. & & ?

  The SAP error message QE300 indicates that there is an issue with the conversion factor for a sample unit of measure (UoM) that has not been maintained for a specific characteristic in the Quality Management (QM) module. This typically occurs when you are trying to record or process quality inspection results, and the system cannot find the necessary conversion factors for the specified characteristic.
  Cause:
  
  Missing Conversion Factor: The primary cause of this error is that the conversion factor for the sample unit of measure has not been defined in the system for the characteristic you are working with.
  Incorrect Configuration: The characteristic may not be properly configured in the system, or the unit of measure settings may not be aligned with the expected values.
  Data Inconsistency: There may be inconsistencies in the master data related to the material or characteristic being used.
  
  Solution:
  To resolve the QE300 error, you can follow these steps:
  
  
  Check Characteristic Configuration:
  
  Go to the transaction code CT04 (Characteristic Maintenance) and check the characteristic that is causing the error.
  Ensure that the characteristic is correctly defined and that the relevant units of measure are maintained.
  
  
  
  Maintain Conversion Factors:
  
  Use transaction code CUNI (Unit of Measure Conversion) to maintain the conversion factors for the sample UoM.
  Ensure that the conversion factors are defined for the characteristic in question.
  
  
  
  Review Material Master Data:
  
  Check the material master data using transaction code MM03 (Display Material) to ensure that the units of measure and characteristics are correctly assigned.
  Verify that the relevant UoM is set up in the material master and that it corresponds to the characteristic.
  
  
  
  Check Inspection Plan:
  
  If you are using an inspection plan, ensure that the plan is correctly configured and that the characteristics and UoMs are properly defined.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for additional guidance on maintaining characteristics and conversion factors.
  
  
  
  Testing:
  
  After making the necessary changes, perform a test to ensure that the error no longer occurs when processing the quality inspection results.
