Specifically, the error states that an association (which is a relationship between two entities) has the same name as a data object (which could be an entity type or a complex type) in your service definition.
  Cause:
  This error typically occurs when:
  
  You have defined an association in your OData model with the same name as an existing entity or complex type.
  There is a naming inconsistency or duplication in your data model, which can happen during the design phase or when merging models.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Conflict:
  
  Check the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Look for the association name mentioned in the error message (&1) and the data object name (&2).
  
  
  
  Rename the Association or Data Object:
  
  If the association and the data object have the same name, you need to rename one of them to ensure that they are unique.

  Adjust the Model:
  
  After renaming, make sure to adjust any references to the renamed association or data object throughout your OData model to maintain consistency.
  
  
  
  Regenerate the Service:
  
  Once the changes are made, regenerate the OData service to apply the updates.
  You can do this in the Service Builder by selecting the service and choosing the "Generate" option.
  
  
  
  Test the Service:
  
  After regeneration, test the OData service to ensure that the error is resolved and that the service behaves as expected.
