This error can occur in various scenarios, such as during the creation or modification of materials, production orders, or other related transactions.
  Cause:
  
  Invalid Unit of Measure: The unit of measure (UoM) specified for a material or transaction is not valid for the context in which it is being used. For example, if you are trying to use a unit of measure that is not defined for a particular material type or in a specific transaction.
