  Solution:

  Review the Data Model: Ensure that your data model is correctly defined and that you are not inadvertently referencing a dynamic view. If necessary, create a new static view that meets the requirements.
  
  
  Consult Documentation: Refer to the SAP documentation for guidelines on using database views and expressions in your specific context. This can provide insights into best practices and limitations.
