• What is the cause and solution for SAP error message /IWBEP/CM_V4_RUNTIME126 - handling=strict is not supported in response if its not requested ?

  The SAP error message /IWBEP/CM_V4_RUNTIME126 indicates that there is an issue with the handling of the handling=strict parameter in an OData service response. This error typically arises when the OData service is configured to use strict handling, but the request does not explicitly request it.
  Cause:
  The error occurs when:
  
  The OData service is set to return responses with handling=strict, but the client (e.g., an application or a browser) does not include this parameter in the request.
  The OData service is expecting a specific handling mode that is not being requested by the client, leading to a mismatch.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the OData Service Configuration:
  
  Ensure that the OData service is correctly configured to handle requests without the handling=strict parameter if it is not required.
  If strict handling is necessary, ensure that the client requests it explicitly.
  
  
  
  Modify the Client Request:
  
  If the client application can be modified, add the handling=strict parameter to the OData request. This can typically be done by appending ?handling=strict to the request URL.
  
  
  
  Review Service Implementation:
  
  If you are developing or maintaining the OData service, review the implementation to ensure that it can handle requests without the handling=strict parameter if that is the desired behavior.
  
  
  
  Check for Updates:
  
  Ensure that you are using the latest version of the SAP Gateway and OData services, as updates may contain fixes for known issues.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for OData services and the specific service you are working with to understand the expected parameters and configurations.
