This error usually occurs when there is an attempt to define a field in a data structure or service that has already been defined elsewhere, leading to a conflict.

  Inconsistent Naming: If there are naming conventions that are not followed, it can lead to confusion and duplicate definitions.
  Model Changes: If the data model has been modified (e.g., fields added or renamed) without proper adjustments in all related definitions, it can lead to this error.
  
  Solution:
  
  Check Field Definitions: Review the data model and service definitions to ensure that each field is defined only once. Look for duplicate field names in the same entity or across related entities.
  Rename Fields: If you find duplicate field names, consider renaming one of the fields to maintain uniqueness.
  Consistency in Naming: Ensure that naming conventions are consistently applied across the model to avoid future conflicts.
  Clear Cache: Sometimes, clearing the cache or refreshing the model in the development environment can help resolve issues related to stale definitions.
  Rebuild the Model: If the issue persists, consider rebuilding the model or regenerating the service to ensure that all definitions are up to date.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation on RAP and data modeling for best practices and guidelines.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
