  The SAP error message /IWBEP/CM_MGW_RT162 indicates that there is an issue with the source name for a complex type in an OData service. This error typically arises when the system expects a source name for a complex type but does not receive one, which can occur during the runtime of an OData service.
  Cause:
  
  Missing Source Name: The error usually occurs when a complex type is defined in the OData service but does not have a corresponding source name in the underlying data model or service implementation.
  Incorrect Mapping: There may be a mismatch between the data model and the OData service definition, leading to the absence of a source name for the complex type.
  Service Implementation Issues: If the service implementation does not correctly handle the complex type or if the metadata is not properly defined, this error can occur.
  
  Solution:
  
  Check Metadata Definition: Ensure that the complex type is correctly defined in the OData service metadata. Verify that the source name is provided for the complex type in the service definition.
  Review Data Model: Check the underlying data model to ensure that the complex type is correctly mapped to the corresponding data source. Make sure that all necessary fields and properties are included.
  Update Service Implementation: If you are implementing the OData service, ensure that the logic for handling the complex type is correctly implemented. This includes ensuring that the source name is being set and passed correctly.
  Regenerate Service: If changes have been made to the data model or service definition, regenerate the OData service to ensure that all changes are reflected in the service implementation.
  Debugging: Use debugging tools to trace the execution of the OData service and identify where the source name is expected but not provided. This can help pinpoint the exact location of the issue.
