• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK259 - Entered DDIC structure &1 not unique; used also in Model &2 for Entity &3 ?

  The SAP error message CFD_REGISTRY_CHECK259 indicates that there is a conflict with the Data Dictionary (DDIC) structure in the context of the SAP Cloud Application Programming (CAP) model. Specifically, it means that the DDIC structure you are trying to use is not unique because it is also being used in another model or entity.
  Cause:
  
  Non-Unique DDIC Structure: The DDIC structure specified in the error message is being referenced in multiple places, which can lead to ambiguity in the data model.
  Model Overlap: The same DDIC structure is defined or used in different models or entities, causing a conflict when the system tries to resolve which one to use.
  
  Solution:
  
  Check DDIC Structure Usage: Review the usage of the DDIC structure in your models. Identify where the structure is being used and ensure that it is not being referenced in multiple places in a way that causes ambiguity.
  Refactor Models: If the DDIC structure is indeed required in multiple models, consider refactoring your models to avoid the overlap. This could involve creating a new, unique structure for one of the models or consolidating the models if appropriate.
  Use Unique Names: Ensure that the names of your entities and models are unique to avoid confusion and conflicts in the future.
  Consult Documentation: Refer to SAP documentation or community forums for guidance on best practices for structuring your models and using DDIC structures.
