  Solution:
  
  Check Entity Definition: Review the entity definition in your CDS (Core Data Services) view or RAP model. Look for any properties that have the same name and ensure that each property is uniquely defined.
  Rename Properties: If you find duplicate property names, rename them to ensure that each property has a unique identifier.
  Review Inheritance: If your entity is inheriting from a base entity, check the base entity for any properties that might be causing the conflict. You may need to override or rename properties in the derived entity.
  Use Annotations: If applicable, use annotations to manage property visibility and conflicts, especially in complex models.
