  The SAP error message M2627 "No unit found, processing of units maintenance canceled" typically occurs in the context of materials management, particularly when dealing with unit of measure (UoM) settings in SAP. This error indicates that the system could not find a valid unit of measure for the material being processed, which prevents the completion of the operation.
  Causes:
  
  Missing Unit of Measure: The material may not have a defined unit of measure in the material master record.
