  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WD140 Element &1 uses proxy structure &2; no support for changes
  
  
  Cause:
  This error occurs in Web Dynpro ABAP when you try to modify (e.g., add, delete, or change) an element of a context node or structure that is based on a proxy structure. Proxy structures are generated automatically by SAP from external service metadata (such as from a Web Service or an RFC proxy). These structures are read-only in the Web Dynpro context because they are tightly coupled to the external service interface.
  In other words, the element &1 (context element) is using a proxy structure &2 (the underlying data type), and SAP does not allow you to change the structure of proxy elements in the Web Dynpro context because they are generated and maintained externally.
  
  Explanation:
  
  Proxy structures are generated from external service definitions (e.g., SOA services, RFC proxies).
  These structures are imported
