• What is the cause and solution for SAP error message WSPT003 - Username and Password are required. ?

  SAP Error Message:
  
  WSPT003 - Username and Password are required.
  
  Cause:
  This error occurs when a web service or a web service consumer in SAP tries to authenticate but the required username and password credentials are missing or not provided. Typically, this happens in scenarios involving:
  
  Web Service Security (WS-Security) where username/password tokens are mandatory.
  SOAP or REST web service calls where authentication is required.
  Configuration of logical ports or web service clients where credentials are not maintained.
  Missing or incorrect entries in the web service consumer proxy or logical port configuration.
  
  
  Solution:
  
  
  Check Logical Port Configuration:
  
  Go to transaction SOAMANAGER.
  Find the logical port used for the web service call.
  Ensure that under the Security tab, the username and password are correctly maintained.
  If the service requires WS-Security UsernameToken, make sure the username and password are entered and saved.
  
  
  
  Maintain Credentials in Consumer Proxy:
  
  If you are using a consumer proxy (transaction SE80 or SPROXY), check if the credentials are set programmatically or via configuration.
  Sometimes, the password needs to be set in the code or via a secure store.
  
  
  
  Check WS-Security Policy:
  
  Verify that the WS-Security policy attached to the web service client requires username/password.
  If yes, ensure the credentials are provided accordingly.
  
  
  
  Programmatic Setting of Credentials:
  
  
  If the web service call is done via ABAP code, ensure that the username and password are set in the proxy before the call, e.g.:
  lo_proxy->set_username( 'username' ).
  lo_proxy->set_password( 'password' ).
  
  
  
  
  Check for Missing or Incorrect Password:
  
  Sometimes the password might be expired or incorrect. Verify the credentials with the target system or service.
  
  
  
  Transport and Secure Storage:
  
  If passwords are stored in secure storage (e.g., Secure Store or SAP Credential Store), verify that the credentials are correctly maintained and accessible.

  Proxy and Logical Port: Understanding the difference between the consumer proxy (ABAP object) and logical port (configuration object) is important.
  Security Policies: WS-Security policies define how authentication is handled; missing or misconfigured policies can cause this error.
  
  
  Summary:
  The error WSPT003 - Username and Password are required indicates missing authentication credentials for a web service call. The solution involves ensuring that the username and password are correctly maintained in the logical port configuration (SOAMANAGER), set programmatically if needed, and that the WS-Security policies are properly configured to require and accept these credentials.
