• What is the cause and solution for SAP error message SEDD_XVIEW012 - HANA View &1 is already used by External View &2 ?

  The SAP error message SEDD_XVIEW012 indicates that there is a conflict in the use of HANA views within the SAP system. Specifically, it means that the HANA view you are trying to create or modify is already being used by an external view. This can happen in scenarios where you are trying to create a new external view that references an existing HANA view, but the system detects that the HANA view is already associated with another external view.
  Cause:
  
  Existing Dependency: The HANA view you are trying to work with is already linked to another external view, which prevents you from using it in a new context.
  View Reusability: HANA views are designed to be reusable, and the system enforces rules to prevent conflicts in their usage.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Views: Identify the external view that is currently using the HANA view. You can do this by checking the dependencies in the HANA studio or using the SAP HANA database explorer.
  
  
  Modify External View: If possible, modify the existing external view to remove the dependency on the HANA view you are trying to use. This may involve changing the logic of the external view or creating a new version of it.
  
  
  Create a New HANA View: If the existing HANA view must remain unchanged, consider creating a new HANA view that replicates the necessary logic or data from the original view. This new view can then be used in your external view without causing conflicts.
  
  
  Consult Documentation: Review SAP documentation or notes related to HANA views and external views for any specific guidelines or best practices that may apply to your situation.
