  SAP Error Message:
  WD217: Comparison value '&' already defined
  
  
  Cause:
  This error occurs in the Web Dynpro ABAP environment when you try to define a comparison value (used in context mapping, value help, or UI element properties) that has already been defined earlier in the same scope.

  There is a copy-paste error or a programming mistake in the Web Dynpro component or view.
