• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK012 - Enter the Extension Include View which you associate in your CDS View ?

  The SAP error message CFD_REGISTRY_CHECK012 typically occurs in the context of Core Data Services (CDS) views when there is an issue with the association of an extension include view. This error indicates that the system expects you to specify an extension include view in your CDS view definition, but it has not been provided or is incorrectly configured.
  Cause:
  
  Missing Extension Include View: The CDS view is expected to have an associated extension include view, but it has not been defined.
  Incorrect Configuration: The extension include view may be incorrectly defined or not activated.
  Syntax Errors: There may be syntax errors in the CDS view definition that prevent the system from recognizing the extension include view.
  Inconsistent Naming: The name of the extension include view may not match the expected naming conventions or may not exist in the system.
  
  Solution:
  
  
  Define the Extension Include View: Ensure that you have created the necessary extension include view that you want to associate with your CDS view. This view should contain the additional fields or logic you want to include.
  
  
  Check Associations: In your CDS view definition, ensure that you have correctly specified the extension include view using the appropriate syntax. For example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AbapCatalog.compiler.compareFilter: true
  define view Z_MY_CDS_VIEW
  as select from my_table
  association to my_extension_include_view as _extension
  on my_table.key = _extension.key
  {
      // Your fields here
  }
  
  
  Activate the Views: Make sure that both the main CDS view and the extension include view are activated. You can do this in the ABAP Development Tools (ADT) or in the SAP GUI.
  
  
  Check for Syntax Errors: Review your CDS view definition for any syntax errors or inconsistencies. Use the syntax check feature in your development environment to identify issues.
  
  
  Review Naming Conventions: Ensure that the naming of your extension include view follows the conventions and that it exists in the system.
