• What is the cause and solution for SAP error message SDDL_PARSER_MSG236 - Composition definitions are not allowed in extend views ?

  The SAP error message SDDL_PARSER_MSG236 indicates that there is an issue with the definition of an extended view in your SAP system. Specifically, the error states that "Composition definitions are not allowed in extend views." This typically occurs when you are trying to create or modify an extended view in a way that is not permitted by the SAP system.
  Cause:
  The error arises when you attempt to use composition definitions (like associations or navigational properties) in an extended view. In SAP, extended views are meant to enhance existing views by adding additional fields or logic, but they do not support the creation of new associations or compositions. This restriction is in place to maintain the integrity and performance of the data model.
  Solution:
  To resolve this error, you should:
  
  
  Review the Extended View Definition: Check the definition of your extended view to ensure that you are not trying to include any composition definitions. Remove any associations or navigational properties that are not allowed.
  
  
  Use Basic Views: If you need to create a view that includes compositions, consider creating a new basic view instead of an extended view. Basic views allow for the definition of associations and compositions.
  
  
  Check Documentation: Refer to the SAP documentation for the specific version you are using to understand the limitations and capabilities of extended views. This will help you design your views correctly.
  
  
  Testing: After making the necessary changes, test the view to ensure that it compiles without errors and behaves as expected.
  
  
  Related Information:
  
  Extended Views: These are used to enhance existing CDS (Core Data Services) views by adding fields or logic without altering the original view.
  Basic Views: These are the foundational views that can include associations and compositions.
  CDS Views: Core Data Services views are a way to define semantic data models in SAP, allowing for complex data retrieval and manipulation.
