• What is the cause and solution for SAP error message DDLS463 - Parent view & must not be extended; extends are not allowed ?

  The SAP error message DDLS463 indicates that you are trying to extend a database view that is defined as a "parent view," which is not allowed in the context of the SAP Data Dictionary. This error typically arises when you attempt to create a new view that extends an existing view that has been marked as non-extendable.
  Cause:
  
  View Definition: The parent view is defined in such a way that it does not allow extensions. This is often the case for standard SAP views or views that have specific constraints.
  Data Dictionary Restrictions: SAP has certain restrictions on extending views to maintain data integrity and consistency. If a view is marked as non-extendable, any attempt to create a new view that extends it will result in this error.
  
  Solution:
  
  Check View Properties: Review the properties of the parent view in the Data Dictionary (transaction SE11). Look for any settings that indicate it is non-extendable.
  Create a New View: Instead of trying to extend the existing view, consider creating a new view that includes the necessary fields from the parent view along with any additional fields you need. This way, you can achieve your goal without violating the extension rules.
  Use a Different Approach: If you need to modify the behavior of the parent view, consider using other methods such as:
  
  Creating a new database table that includes the necessary fields and then creating a view on top of that.
  Using a different type of object, such as a table function or a CDS view, if applicable.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on view definitions and restrictions.
  
  Related Information:
  
  Transaction Codes: Use transaction SE11 to view and edit Data Dictionary objects, including views.
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or solutions related to this error.
