• What is the cause and solution for SAP error message LR271 - Unit & not permitted with a confirmation ?

  The SAP error message LR271 ("Unit & not permitted with a confirmation") typically occurs in the context of inventory management or production processes when there is a mismatch between the unit of measure (UoM) used in a transaction and the unit of measure defined in the system for the material or product being processed.
  Cause:
  
  Unit of Measure Mismatch: The unit of measure used in the confirmation does not match the unit of measure defined for the material in the material master.
  Configuration Issues: The configuration settings for the material or the movement type may not allow for the specified unit of measure to be used in confirmations.
  Incorrect Settings in the Material Master: The material master may not be set up correctly to allow for the unit of measure being used in the confirmation.
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03) and check the units of measure defined for the material. Ensure that the unit you are trying to use in the confirmation is listed as a valid unit of measure.
  
  
  
  Review Confirmation Settings:
  
  Check the confirmation settings in the production order or the relevant transaction. Ensure that the unit of measure used in the confirmation is allowed for that specific order type or movement type.
  
  
  
  Adjust Configuration:
  
  If necessary, adjust the configuration settings in the system to allow for the use of the desired unit of measure. This may involve working with your SAP configuration team to ensure that the relevant movement types and order types are set up correctly.
  
  
  
  Use Correct Unit of Measure:
  
  If the unit of measure you are trying to use is not permitted, consider using a different unit of measure that is allowed for the confirmation process.
