  The SAP error message "NEXUS000 Invalid XML file: '&'" typically indicates that there is an issue with the XML file being processed by the SAP system. This error can arise due to various reasons, including malformed XML syntax, invalid characters, or issues with the structure of the XML document.
  Causes:
  
  Malformed XML: The XML file may not adhere to proper XML syntax rules. This includes missing tags, unclosed tags, or incorrect nesting of elements.
  Invalid Characters: The presence of special characters (like &, <, >, etc.) that are not properly escaped can lead to this error. For example, the ampersand (&) should be represented as &amp; in XML.
  Encoding Issues: The XML file may not be encoded correctly (e.g., UTF-8), leading to misinterpretation of characters.

  Check Encoding: Make sure the XML file is saved with the correct encoding (preferably UTF-8). You can check and change the encoding in text editors or IDEs.
  Review Schema Compliance: If applicable, ensure that the XML file adheres to the required schema or DTD. Validate the XML against the schema to identify any discrepancies.
