  SAP Error Message:
  
  WSS024 - Error while creating wsse:UsernameToken
  
  Cause:
  This error typically occurs during the creation of the WS-Security UsernameToken in SAP Web Services Security (WS-Security) processing. The wsse:UsernameToken is part of the WS-Security standard used to provide username/password authentication tokens in SOAP headers.
  Common causes include:
  
  Incorrect or missing configuration of WS-Security in the SAP system.
  Missing or invalid user credentials (username or password) when generating the token.
  Issues with password handling, such as unsupported password types or missing password digest.
  Problems in the security policy or security profile assigned to the web service.
  Missing or incorrect SAP kernel patches or support packages related to WS-Security.
  Incorrect or missing cryptographic libraries or settings required for password digest or encryption.
  Programming errors in custom code that generates or manipulates the UsernameToken.
  
  
  Solution:
  To resolve the WSS024 error, consider the following steps:
  
  
  Check WS-Security Configuration:
  
  Verify that the WS-Security profile assigned to the web service is correctly configured.
  Ensure that the security policy includes the UsernameToken with the correct password type (PlainText or Digest).
  Use transaction STRUST to check certificates if encryption or signing is involved.
  
  
  
  Validate User Credentials:
  
  Confirm that the username and password used for the token are correct and not empty.
  If using password digest, ensure the password is correctly hashed and the nonce and timestamp are properly generated.
  
  
  
  Review Security Policy and Profile:
  
  In SOAMANAGER, check the security policy assigned to the web service binding.
  Make sure the policy supports UsernameToken and that the password type matches the client and server expectations.
  
  
  
  Check SAP Notes and Patches:
  
  Look for relevant SAP Notes that address WS-Security issues or bugs related to UsernameToken creation.
  Apply any necessary kernel patches or support packages.
  
  
  
  Debug and Trace:
  
  Enable detailed logging for WS-Security in the SAP system to get more information.
  Use transaction SICF to check the web service and enable trace.
  Debug the ABAP code if custom UsernameToken creation is implemented.
  
  
  
  Verify Cryptographic Settings:
  
  Ensure that the SAP Cryptographic Library (CommonCryptoLib) is installed and configured properly.
  Check that the system time is synchronized, as timestamps are critical for token validity.
  
  
  
  Check for Programming Errors:
  
  If the UsernameToken is created via custom code (e.g., in ABAP proxy or handler), verify the code logic.
  Make sure the XML structure of the UsernameToken is correctly formed.
  
  
  
  
  Related Information:
  
  
  WS-Security UsernameToken Profile:
