• What is the cause and solution for SAP error message SEEF_BASE090 - No POST method exists for & ?

  The SAP error message SEEF_BASE090 with the description "No POST method exists for &" typically occurs when there is an attempt to call a service or function that does not support the HTTP POST method. This can happen in various scenarios, especially when working with SAP Gateway services or OData services.
  Cause:
  
  Unsupported HTTP Method: The service you are trying to access is not configured to handle POST requests. This could be due to the service being read-only or not having the necessary implementation for creating or updating resources.
  Incorrect URL: The URL being accessed may not correspond to a valid endpoint that supports POST operations.
  Service Configuration: The service might not be properly configured in the SAP Gateway or the backend system, leading to the absence of the required POST method.
  
  Solution:
  
  Check Service Implementation: Verify that the service you are trying to call is implemented correctly and supports the POST method. You can do this by checking the service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Review the URL: Ensure that the URL you are using is correct and points to the right endpoint that is designed to handle POST requests.
  Service Registration: Make sure that the service is registered and activated in the SAP Gateway. You can check this in the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) or through the SAP Gateway Service Maintenance (transaction code /IWFND/MAINT_SERVICE).
  Check Authorization: Ensure that the user has the necessary authorizations to perform POST operations on the service.
  Debugging: If you have access to the backend, you can debug the service to see if there are any issues in the implementation that prevent the POST method from being recognized.
  
  Related Information:
  
  SAP Gateway: Understand how SAP Gateway services work, including the different HTTP methods (GET, POST, PUT, DELETE) and their intended use cases.
  OData Services: Familiarize yourself with OData protocol specifications, as they define how services should handle different types of requests.
  SAP Notes: Check for any relevant SAP Notes or documentation that might address known issues or provide additional guidance on this error message.
