  The SAP error message /IWBEP/CM_V4_MED174 indicates that there is an issue with setting a unit property in an OData service. The specific message states that the property &1 has an invalid conversion type. This typically occurs when there is a mismatch between the expected data type of a property and the actual data type being provided.
  Cause:
  
  
  Data Type Mismatch: The property you are trying to set has a defined data type in the OData model that does not match the type of the value you are trying to assign to it. For example, if the property is defined as a Decimal type but you are trying to assign a String value.
  
  
  Incorrect Metadata: The metadata of the OData service may not be correctly defined, leading to inconsistencies in how properties are interpreted.
  
  
  Unit of Measure Issues: If the property is expected to have a unit of measure (UoM) and the value being passed does not conform to the expected format or type, this error can occur.
  
  
  Service Versioning: If there are changes in the OData service version and the client is not updated accordingly, it may lead to such errors.
  
  
  Solution:
  
  
  Check Data Types: Verify the data type of the property in the OData service metadata. Ensure that the value you are trying to set matches the expected data type.
  
  
  Review OData Model: Check the OData model definition to ensure that the property is correctly defined with the appropriate data type and unit of measure.
  
  
  Update Client Code: If you are using a client application to interact with the OData service, ensure that the client code is updated to match the current service definition.
  
  
  Test with Valid Data: Try to set the property with a known valid value that matches the expected data type and format.
  
  
  Check for Unit of Measure: If the property involves units, ensure that the unit of measure is correctly specified and that the value is compatible with it.
  
  
  Debugging: Use debugging tools to trace the request and response to see what data is being sent and received. This can help identify where the mismatch is occurring.
  
  
  Related Information:
