• What is the cause and solution for SAP error message WSPT007 - Error "&" while creating Binary table from NONCE string. ?

  Certainly! Here's a detailed explanation regarding the SAP error message:
  
  SAP Error Message:
  WSPT007 Error "&" while creating Binary table from NONCE string
  
  Cause:
  This error typically occurs in the context of SAP Web Services Security (WS-Security) processing, specifically when handling the NONCE value in security tokens.
  
  The NONCE is a random or pseudo-random number used once to prevent replay attacks.
  The error indicates that while converting the NONCE string into a binary table (internal byte array), an unexpected character "&" is encountered.
  This usually happens because the NONCE string contains invalid or unexpected characters that cannot be properly decoded or converted.
  The NONCE string is often Base64 encoded; if the string is corrupted, malformed, or contains illegal characters (like &), the decoding fails.
  Possible causes:
  
  Incorrect or corrupted NONCE value in the SOAP header.
  Encoding issues (e.g., NONCE not properly Base64 encoded).
  Interference or modification of the message in transit.
  Custom or third-party tools altering the security header.
  
  
  
  
  Solution:
  
  
  Check the NONCE value:
  
  Verify that the NONCE string in the WS-Security header is correctly Base64 encoded.
  Ensure it does not contain illegal characters such as &, <, >, or other XML special characters that are not properly escaped.
  
  
  
  Validate the SOAP message:
  
  Use a SOAP message analyzer or XML tool to inspect the WS-Security header.
  Confirm that the NONCE element is well-formed and correctly encoded.
  
  
  
  Check encoding and escaping:
  
  If the NONCE string is embedded in XML, ensure that special characters are properly escaped or encoded.
  For example, & should be represented as &amp; in XML.
  
  
  
  Review the client sending the request:
  
  If you are consuming a web service, check the client application generating the WS-Security header.
  Ensure it correctly generates and encodes the NONCE value.
  
  
  
  SAP Notes and Patches:
  
  Check for relevant SAP Notes related to WS-Security and NONCE handling.
  Sometimes, patches or support packages fix known issues with security token processing.
  
  
  
  Debugging:
  
  Enable detailed logging for WS-Security processing in SAP.
  Trace the inbound SOAP message and the point of failure.
  Use transaction STRUST or SOAMANAGER to check security configurations.
  
  
  
  
  Related Information:
  
  
  WS-Security Specification: NONCE is part of the UsernameToken profile to prevent replay attacks.
  
  
  Base64 Encoding: NONCE values are Base64 encoded binary data.
  
  
  SAP Web Service Security: SAP uses standard WS-Security processing; errors in token decoding can cause failures.
  
  
  SAP Transactions:  
  
  SOAMANAGER - Web Service configuration and security settings.  
  STRUST - Manage certificates and security tokens.  
  SMICM / SMGW - For monitoring communication.
  
  
  
  SAP Notes:
  
  Search for notes with keywords like "WSPT007", "NONCE", "WS-Security", "Base64 decoding error".
  
  
  
  Summary:
  
  
  
  Aspect
  Details
  
  
  
  
  Cause
  Invalid or malformed NONCE string containing illegal character & during Base64 decoding.
  
  
  Solution
  Verify and correct the NONCE string encoding; ensure proper escaping of XML special chars; check client and server WS-Security configurations.
