• What is the cause and solution for SAP error message DDLS397 - Parent view & contains selection list interface: Extend view not possible ?

  The SAP error message DDLS397 indicates that there is an issue with extending a view in the Data Dictionary (DDLS) due to the presence of a selection list interface in the parent view. This typically occurs when you are trying to extend a view that has a selection list interface, which is not allowed in SAP.
  Cause:
  The error arises because:
  
  The parent view has a selection list interface, which means it is designed to provide a selection list for the data it retrieves.
  Extending such views is not permitted in SAP, as it can lead to inconsistencies or complications in the data retrieval process.
  
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Check the Parent View: Review the parent view to understand its structure and the reason it has a selection list interface. If the selection list is not necessary, you might consider modifying the parent view to remove it, if feasible.
  
  
  Create a New View: Instead of extending the existing view, you can create a new view that meets your requirements. This new view can reference the parent view without the selection list interface.
  
  
  Use a Different Approach: If your goal is to add additional fields or functionality, consider using other methods such as:
  
  Creating a new database table and using it in conjunction with the existing view.
  Using a different type of view that does not have the selection list interface.
  
  
  
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or ABAP team for best practices regarding view extensions and the implications of selection list interfaces.
