/IWBEP/CM_V4_MED236 - Details

• The SAP error message /IWBEP/CM_V4_MED236 indicates that there is an issue with the return type of an operation in an OData service. Specifically, it states that the return type of the operation is a collection of complex types, which is not supported in the context of the operation being executed.
  
  Cause:
  
  
  Return Type Definition: The operation (such as a function import or an entity set) is defined to return a collection of complex types, but OData services typically do not support returning collections of complex types directly. Instead, they expect either a single entity, a collection of entities, or a primitive type.
  
  
  Service Implementation: The implementation of the OData service may be incorrectly configured to return a collection of complex types instead of a collection of entities or a single entity.
  
  
  Model Definition: The data model defined in the service might be incorrectly set up, leading to the generation of an unsupported return type.
