• What is the cause and solution for SAP error message /IWBEP/CM_CP128 - Unit property missing: Entity Type '&1', property '&2', unit prop. '&3' ?

  The SAP error message /IWBEP/CM_CP128 indicates that there is a missing unit property for a specific entity type and property in your OData service. This error typically arises when the OData model is not correctly defined or when the metadata for the entity type does not include the necessary unit information for a property that is expected to have one.
  Cause:
  
  Missing Unit Property Definition: The entity type defined in your OData service does not have a unit property defined for a specific property that requires it.
  Incorrect Metadata: The metadata for the OData service may not be correctly configured, leading to discrepancies between the expected and actual definitions.
  Model Configuration Issues: There may be issues in the way the OData model is configured in the backend, such as missing annotations or incorrect data types.
  
  Solution:
  
  
  Check Entity Type Definition:
  
  Go to the Data Model (e.g., in SEGW transaction) and check the entity type definition for the specified entity type (&1).
  Ensure that the property (&2) has a corresponding unit property (&3) defined.
  
  
  
  Define Unit Property:
  
  If the unit property is missing, you need to define it in the entity type. This can be done by:
  
  Adding a new property for the unit in the entity type.
  Ensuring that the property is correctly annotated with the unit of measure.
  
  
  
  
  
  Update Metadata:
  
  After making changes to the entity type, regenerate the metadata for the OData service. This can usually be done in the SEGW transaction by right-clicking on the service and selecting "Generate Runtime Objects".
  
  
  
  Check Annotations:
  
  Ensure that the annotations for the properties are correctly set up, especially for properties that require units of measure.
  
  
  
  Test the OData Service:
  
  After making the necessary changes, test the OData service to ensure that the error is resolved and that the unit properties are being returned correctly.
