  The SAP error message VSMI078, which states "Unable to convert unit of measurement '&1' into the internal format," typically occurs when there is an issue with the unit of measurement (UoM) being used in a transaction or process. This error can arise in various contexts, such as during material movements, inventory management, or when processing sales orders.
  Causes:
  
  Invalid Unit of Measurement: The UoM specified may not be defined in the system or may not be valid for the material or transaction type being processed.
  Configuration Issues: There may be configuration issues in the unit of measurement settings in the SAP system.
  Data Inconsistencies: There could be inconsistencies in the master data, such as the material master or the UoM conversion factors.
  Missing Conversion Factors: If the UoM requires conversion to another UoM and the conversion factors are not defined, this error can occur.
