• What is the cause and solution for SAP error message /IWBEP/CM_V4_ANNO035 - Annotation target &1 is already defined ?

  The SAP error message /IWBEP/CM_V4_ANNO035 indicates that there is a conflict in the definition of an annotation target in your OData service. Specifically, it means that the annotation target you are trying to define is already defined elsewhere in your service or in the metadata.
  Cause:
  
  Duplicate Annotations: The most common cause of this error is that the same annotation target is being defined multiple times in your OData service.
  Incorrect Metadata: There may be issues in the metadata where the same entity or property is being annotated more than once.
  Versioning Issues: If you are working with different versions of the service or have made changes that are not properly reflected in the metadata, this can lead to conflicts.
  
  Solution:
  
  Check for Duplicates: Review your annotation definitions in the service to ensure that you are not defining the same target multiple times. Look for duplicate entries in your annotation files or in the service implementation.
  Review Metadata: Use the OData metadata document (usually accessible via a URL like /sap/opu/odata/sap/<service_name>/$metadata) to inspect the definitions and see where the conflict arises.
  Clear Cache: If you have made changes to the annotations, clear any caches that might be holding onto old metadata. This can include clearing the cache in the SAP Gateway or in your development environment.
  Adjust Annotations: If you find that the same annotation is necessary for different contexts, consider using different targets or restructuring your annotations to avoid conflicts.
  Check for Inheritance: If you are using inheritance in your OData model, ensure that the annotations are not being inherited in a way that causes conflicts.
