  Typographical Error: There may be a typo in the column name or the source table/view name.
  Incorrect Source Definition: The source table or view may not be correctly defined or may have been changed (e.g., columns added or removed).

  Check for Transport Issues: If the issue arose after a transport, ensure that all necessary objects were transported correctly and that the target system is in sync with the development environment.
  
  Related Information:
  
  Transaction Codes: Use SE11 (Data Dictionary) to check the structure of tables and views, and SE80 (Object Navigator) to manage and view your CDS views.
