SECATT_HTTP_STATUS417 - Details

• The SAP error message "SECATT_HTTP_STATUS417 Expectation Failed" typically occurs when there is an issue with the HTTP request being sent from the SAP system to a web service or an external system. The HTTP status code 417 indicates that the server cannot meet the requirements of the Expect request-header field.
  
  Cause:
  
  Expect Header: The client (SAP system) is sending an "Expect: 100-continue" header in the HTTP request, which indicates that the client expects the server to respond with a 100 (Continue) status before sending the request body. If the server does not support this expectation, it will respond with a 417 status code.
  Server Configuration: The server you are trying to communicate with may not be configured to handle the "Expect" header properly.
  Network Issues: There could be network-related issues that prevent the request from being processed correctly.
  Proxy Issues: If there is a proxy server involved, it may not be handling the Expect header
