  The SAP error message MG271 ("Transaction & record &: unit record without unit not processed") typically occurs in the context of inventory management and material movements. This error indicates that there is an issue with the unit of measure (UoM) for a material transaction. Specifically, it suggests that a record is being processed without a valid unit of measure, which is essential for inventory transactions.
  Causes:
  
  Missing Unit of Measure: The material master record may not have a defined base unit of measure or the unit of measure for the transaction is not specified.
