• What is the cause and solution for SAP error message /IWBEP/CM_MGW_GENER035 - Found non-unique complex type name '&1' for field '&2' ?

  The SAP error message /IWBEP/CM_MGW_GENER035 indicates that there is a non-unique complex type name in your OData service definition. This typically occurs when two or more complex types in your service have the same name, which leads to ambiguity when the service is being generated or consumed.
  Cause:
  
  
  Duplicate Complex Type Names: The most common cause of this error is that there are multiple complex types defined with the same name in your OData service. This can happen if:
  
  You have defined the same complex type in different entities or contexts.
  You have imported multiple data sources that contain complex types with the same name.
  
  
  
  Namespace Issues: If complex types are defined in different namespaces but have the same name, it can also lead to this error.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Duplicate Complex Types:
  
  Check the definitions of your complex types in the OData service. Look for any complex types that share the same name.
  You can do this by navigating to the Data Model in the SAP Gateway Service Builder (transaction code SEGW) and reviewing the complex types defined.
  
  
  
  Rename or Remove Duplicates:
  
  If you find duplicate complex types, you can either rename them to ensure uniqueness or remove the unnecessary duplicates.
  Make sure to update any references to the renamed complex types in your entities.
  
  
  
  Check Namespaces:
  
  If you are using namespaces, ensure that complex types are properly namespaced to avoid conflicts. You can define a unique namespace for each complex type to prevent naming collisions.
  
  
  
  Regenerate the Service:
  
  After making the necessary changes, regenerate the OData service to ensure that the changes take effect. You can do this in the Service Builder by selecting the service and choosing the "Generate" option.
  
  
  
  Test the Service:
  
  Once the service is regenerated, test it to ensure that the error is resolved and that the service behaves as expected.
