• What is the cause and solution for SAP error message /IWFND/CM_MGW103 - This service use Read Access Logging. X-CSRF token is required. ?

  The SAP error message /IWFND/CM_MGW103 indicates that a service is using Read Access Logging (RAL) and requires a Cross-Site Request Forgery (CSRF) token for the request. This is a common issue when working with OData services in SAP Gateway.
  Cause:
  
  Read Access Logging (RAL): When RAL is enabled for an OData service, it requires a CSRF token to be included in the request headers to prevent CSRF attacks.
  Missing CSRF Token: The error occurs when the client application does not send a valid CSRF token in the request headers.
  Incorrect HTTP Method: If you are trying to perform a read operation (GET) without first obtaining a CSRF token, the service will reject the request.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Obtain the CSRF Token:
  
  Before making a GET request to the OData service, you need to perform a GET request to the service's metadata or a specific entity set to obtain the CSRF token.
  The CSRF token can be found in the response headers under X-CSRF-Token.
  
  Example of obtaining the CSRF token:
  GET /sap/opu/odata/sap/YOUR_SERVICE_NAME/$metadata HTTP/1.1
  Host: your_sap_host
  Check the response headers for X-CSRF-Token.
  
  
  Include the CSRF Token in Subsequent Requests:
  
  Once you have the CSRF token, include it in the headers of your subsequent requests (e.g., GET, POST, PUT, DELETE).
  The header should look like this:
  X-CSRF-Token: <your_csrf_token>
  
  
  
  
  Check Service Configuration:
  
  Ensure that the OData service is correctly configured to use Read Access Logging and that the necessary authorizations are in place.
  
  
  
  Testing:
  
  After implementing the above steps, test your requests to ensure that the error no longer occurs.
