UD399 - Details

• The SAP error message UD399 indicates that a specific view (denoted as &1) has not been deleted from the Data Dictionary. This error typically arises when you attempt to delete a database object (like a table or a view) that is still referenced in the Data Dictionary.
  
  Cause:
  
  Existing References: The view you are trying to delete is still being referenced by other objects in the Data Dictionary, such as other views, tables, or programs.
  Inconsistent State: The system may be in an inconsistent state where the view is marked for deletion but still exists in the database.
  Authorization Issues: You may not have the necessary authorizations to delete the view or related objects.
  
  
  Solution:
  
  
  Check Dependencies: Use transaction code SE11 (Data Dictionary) to check for dependencies of the view. Look for any objects that reference the view and address those dependencies before attempting to delete it.
