• What is the cause and solution for SAP error message WD170 - Error '&' when converting data '&' to XML ?

  The SAP error message:
  WD170 Error '&' when converting data '&' to XML
  typically occurs in the context of Web Dynpro applications or any SAP component that involves converting data structures to XML format.
  
  Cause
  
  The error indicates that during the conversion of data to XML, an invalid or unexpected character (in this case, the ampersand &) was encountered.
  The ampersand & is a special character in XML and must be properly escaped (e.g., &) when included in XML content.
  If the data contains special characters like &, <, >, ", or ' and these are not properly escaped, the XML parser will throw an error.
  This usually happens when the data being converted to XML contains raw special characters that violate XML syntax rules.
  
  
  Solution
  
  
  Escape Special Characters:
  
  Ensure that all special characters in the data are properly escaped before conversion to XML.
  SAP provides standard functions to escape XML special characters, such as:
  CL_WD_XML_UTILITIES=>ESCAPE_XML
  Or use the method CL_WD_XML_UTILITIES=>ESCAPE_XML to convert
