  Cause:
  
  Missing or Incorrect Definition: The complex type may not be defined correctly in the Data Dictionary (DDIC) or in the OData service metadata.
  Inconsistent Data Model: There may be inconsistencies in the data model, such as missing associations or incorrect mappings.
  Transport Issues: If the OData service was transported from one system to another, there may be missing dependencies or objects.
