  The SAP error message 0S165 indicates that the HTTP trace has not been activated. This error typically occurs when you are trying to analyze HTTP requests and responses in the SAP system, but the tracing functionality is not enabled.
  Cause:
  The primary cause of this error is that the HTTP trace feature in the SAP system is not activated. This can happen for several reasons:
  
  The HTTP trace has not been configured or enabled in the system settings.
  The user does not have the necessary authorizations to activate the HTTP trace.
  The system may be in a state where tracing is not allowed (e.g., production systems may have tracing disabled for performance reasons).
  
  Solution:
  To resolve the error 0S165, you can follow these steps:
  
  
  Activate HTTP Trace:
  
  Go to transaction code SICF (HTTP Service Hierarchy Maintenance).
  Navigate to the service you want to trace (e.g., the service for your application).
  Right-click on the service and select "Trace" to activate the HTTP trace.
  Alternatively, you can use transaction ST01 (System Trace) to enable HTTP tracing.
  
  
  
  Check Authorizations:
  
  Ensure that your user has the necessary authorizations to activate and view HTTP traces. You may need to consult with your SAP security team to verify your roles and permissions.
  
  
  
  Use Transaction ST01:
  
  Open transaction ST01.
  Select the "HTTP" option and activate the trace.
  Perform the actions that led to the error, and then deactivate the trace to analyze the results.
  
  
  
  Check System Settings:
