  The SAP error message EI461, which states "Unit of measurement & not defined in the system," typically occurs when the system encounters a unit of measurement (UoM) that has not been defined or configured in the SAP system. This can happen in various contexts, such as during the creation of materials, purchase orders, or sales orders.
  Cause:
