  The SAP error message /UI2/FND405 Request method &1 is not supported by the resource typically indicates that a request was made to a resource (such as an OData service) using an HTTP method that is not supported by that resource. The &1 in the message will be replaced by the actual HTTP method that was attempted (e.g., GET, POST, PUT, DELETE).
  Cause:
  
  Unsupported HTTP Method: The most common cause is that the HTTP method used in the request is not implemented or allowed for the specific OData service or resource.
  Incorrect URL: The URL being accessed may not correspond to a valid endpoint for the specified HTTP method.
  Service Configuration: The OData service may not be properly configured to handle the requested method.
  Authorization Issues: Sometimes, the user may not have the necessary permissions to perform the requested operation, leading to a similar error.
  
  Solution:
  
  
  Check the HTTP Method: Verify that you are using the correct HTTP method for the operation you are trying to perform. For example:
  
  Use GET for retrieving data.
  Use POST for creating new entries.

  Check Service Implementation: If you have access to the backend, check the implementation of the OData service to ensure that it supports the requested method.

  Related Information:
