• What is the cause and solution for SAP error message /IWFND/CM_MGW394 - Context token requests has incorrect "sap-language" URL parameter ?

  The SAP error message /IWFND/CM_MGW394 indicates that there is an issue with the "sap-language" URL parameter in a context token request. This error typically occurs in the context of SAP Gateway services, particularly when dealing with OData services.
  Cause:
  The error is caused by an incorrect or missing "sap-language" parameter in the URL of the request. The "sap-language" parameter is used to specify the language in which the response should be returned. If this parameter is not provided, is incorrectly formatted, or contains an unsupported language code, the SAP Gateway cannot process the request correctly.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the URL: Ensure that the URL used for the context token request includes the "sap-language" parameter. The parameter should be formatted correctly, for example:
  .../sap/opu/odata/sap/YOUR_SERVICE_NAME/?sap-language=EN
  
  
  Validate Language Code: Make sure that the language code provided in the "sap-language" parameter is valid and supported by your SAP system. Common language codes include:
  
  EN for English
  DE for German
  FR for French
  etc.
  
  
  
  Default Language Setting: If the "sap-language" parameter is not explicitly set in the request, check the default language settings in your SAP system. The system may have a default language configured that can be used if the parameter is omitted.
  
  
  Check Client Configuration: If you are using a client application (like SAP Fiori or a custom application), ensure that it is correctly configured to send the "sap-language" parameter in its requests.
  
  
  Review Gateway Configuration: If the issue persists, review the configuration of the SAP Gateway service to ensure that it is set up to handle language parameters correctly.
  
  
  Debugging: If you have access to the backend, you can use transaction codes like /IWFND/ERROR_LOG to check for more detailed error logs that might provide additional context about the issue.
