  The SAP error message "CFD_REGISTRY_CHECK100 DDIC Include &1 cannot be reused for different extensibility purpose" typically occurs in the context of SAP's Core Data Services (CDS) and extensibility framework. This error indicates that a Data Dictionary (DDIC) include is being reused in a way that is not allowed due to conflicting extensibility purposes.
  Cause:

SAP enforces strict rules regarding the reuse of DDIC includes to maintain data integrity and consistency.

  Solution:
  
  Check Usage of DDIC Include: Review where the DDIC include is being used in your CDS views or other objects. Ensure that it is not being reused in a conflicting manner.
  Create Separate Includes: If the same structure is needed for different purposes, consider creating separate DDIC includes for each extensibility purpose. This will help avoid conflicts and adhere to SAP's guidelines.
  Review Extensibility Settings: Ensure that the extensibility settings for your CDS views or entities are correctly configured and do not conflict with the usage of the DDIC include.
  Consult Documentation: Refer to SAP documentation regarding the extensibility framework and CDS views to understand the rules and best practices for using DDIC includes.

  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance on best practices for using DDIC includes.
