• What is the cause and solution for SAP error message SDDL_PARSER_MSG128 - The view & contains a UNION and cannot be extended ?

  The SAP error message SDDL_PARSER_MSG128 indicates that you are trying to extend a view that contains a UNION operation. In SAP, views that are defined with a UNION cannot be extended because the structure of the data returned by a UNION is not compatible with the extension mechanism.
  
  Cause:
  The primary cause of this error is that the view you are attempting to extend is defined using a UNION operation. A UNION combines the results of two or more SELECT statements into a single result set, and this structure does not allow for the addition of new fields or modifications through extensions.
  
  Solution:
  To resolve this error, you have a few options:
  
  
  Create a New View: Instead of trying to extend the existing view, you can create a new view that combines the necessary fields from the original view and any additional fields you need. This new view can be designed without a UNION or
