• What is the cause and solution for SAP error message /IWFND/CM_MGW_RT162 - Source name for complex type '&1' was not provided ?

  The SAP error message /IWFND/CM_MGW_RT162 indicates that there is an issue with the definition of a complex type in an OData service. Specifically, the error message states that the source name for a complex type has not been provided. This typically occurs when the OData service is trying to map a complex type but cannot find the necessary source name to do so.
  Cause:
  
  Missing Source Name: The complex type in the OData service definition does not have a source name defined. This can happen if the complex type is not properly configured in the service or if there is a mismatch in the metadata.
  Incorrect Mapping: The mapping between the complex type and the underlying data model (e.g., database table or structure) is not correctly set up.
  Service Definition Issues: There may be issues in the service definition or the way the service is generated, leading to incomplete or incorrect metadata.
  
  Solution:
  
  
  Check the Complex Type Definition:
  
  Go to the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Locate the complex type that is causing the issue and ensure that it has a valid source name defined.
  
  
  
  Update the Metadata:
  
  If the source name is missing, you may need to add it manually or regenerate the metadata for the service.
  Right-click on the service in the Service Builder and select "Generate" to regenerate the service and its metadata.
  
  
  
  Review the Mapping:
  
  Ensure that the mapping between the complex type and the underlying data source (like a database table or structure) is correctly defined.
  Check the properties of the complex type and ensure that they are correctly mapped to the corresponding fields in the data source.
  
  
  
  Test the Service:
  
  After making the necessary changes, test the OData service using the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to ensure that the error is resolved.
  
  
  
  Check for Transport Issues:
  
  If the service was transported from one system to another, ensure that all dependencies and related objects were also transported correctly.
