  SAP Error Message:
  WD171 Error '&' during XML import of data '&'
  
  Cause:
  This error occurs during the import of XML data into an SAP Web Dynpro application or component. The message indicates that there was a problem processing the XML data, often due to:
  
  Malformed or invalid XML structure.
  Unexpected or illegal characters in the XML data.
  Mismatch between the expected XML schema and the actual data.

  Solution:
  To resolve the WD171 error, consider the following steps:

  Ensure that all tags are properly closed and nested.
  
  
  
  Check Encoding:
  
  Verify that the XML file encoding matches what the SAP system expects (usually UTF-8).
  Special characters (like &, <, >, ', ") should be properly escaped (e.g., &, <, >, ', ").
  
  
  
  Review the XML Structure:
  
  Compare the XML structure against the Web Dynpro component’s expected data model.
  Make sure all required elements and attributes are present and correctly named.
