• What is the cause and solution for SAP error message DDLS398 - View contains selection list interface: Extend views then not possible ?

  The SAP error message DDLS398 indicates that a view contains a selection list interface, which means that the view is designed to allow users to select multiple entries from a list. However, when you try to extend such a view, the system does not allow it due to the constraints imposed by the selection list interface.
  Cause:
  The primary cause of this error is that the view you are trying to extend is defined in a way that it includes a selection list interface. In SAP, certain views are designed to be used with selection lists, and extending them directly is not permitted because it could lead to inconsistencies or issues in how the selection list operates.
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Create a New View: Instead of trying to extend the existing view, create a new view that meets your requirements. You can replicate the necessary fields and logic from the original view without the selection list interface.
  
  
  Modify the Existing View: If you have the necessary authorizations and it is appropriate for your project, you could modify the existing view to remove the selection list interface. However, this approach should be taken with caution, as it may affect other functionalities that rely on the original view.
  
  
  Use a Different Approach: Depending on your requirements, you might be able to achieve your goals using a different method, such as using a table function or a different type of view that does not have the selection list interface.
  
  
  Consult Documentation: Review the SAP documentation related to the specific view and its intended use. This can provide insights into how to work with the view and any limitations that may apply.
  
  
  Seek Help from SAP Support: If you are unsure how to proceed or if the view is critical to your operations, consider reaching out to SAP support for guidance.
