  The SAP error message /IWFND/CM_MGW_RT140 No complex type found for complex type property '&1' typically occurs in the context of SAP Gateway and OData services. This error indicates that the system is unable to find a definition for a complex type that is referenced in your OData service model.
  Cause:
  
  Missing Complex Type Definition: The complex type that is being referenced in your OData service is not defined in the data model.
  Incorrect Metadata: The metadata of the OData service may not be correctly defined or may be missing the necessary complex type definitions.
  Model Binding Issues: There may be issues with how the data model is bound to the OData service, leading to the inability to resolve the complex type.
  Changes in Data Model: If there have been recent changes to the data model (like renaming or deleting complex types), the OData service may not have been updated accordingly.
  
  Solution:
  
  
  Check Complex Type Definition:
  
  Go to the Data Model (e.g., in SEGW transaction) and ensure that the complex type referenced in the error message is defined correctly.

  Check Metadata:

  Rebuild the Service:
  
  If the issue persists, consider rebuilding the OData service. This can be done by deleting the service and recreating it, ensuring that all complex types are correctly defined.
  
  
  
  Check for Naming Issues:
  
  Ensure that there are no typos or naming inconsistencies in the complex type names in your data model and the OData service.
  
  
  
  Debugging:
