  The SAP error message SRT_WSP3284 indicates that there is a mismatch between the authentication method being used and the authentication methods allowed for a specific service definition in SAP. This error typically occurs in the context of web services, particularly when using SAP's Web Services Runtime (WSR).
  Cause:
  The error message is triggered when:

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Service Definition:

  If the client is using a different method (e.g., Basic Authentication, WS-Security, etc.), modify the client configuration to match one of the allowed methods.
  
  
  
  Modify Service Definition (if necessary):
  
  If you need to allow a different authentication method, you can modify the service definition in SOAMANAGER.
  Be cautious when changing security settings, as this can have implications for the security of your web service.
