Smart SAP Assistant

• What is the cause and solution for SAP error message /IWFND/CM_MGW392 - Context token requests also need "sap-language" as URL parameter ?

  The SAP error message /IWFND/CM_MGW392 indicates that a context token request in an OData service is missing the required sap-language parameter in the URL. This parameter is essential for the system to determine the language in which the response should be returned.
  Cause:
  The error occurs when a request is made to an OData service without including the sap-language parameter. This parameter is necessary for the SAP Gateway to process the request correctly and return the appropriate language-specific data.
  Solution:
  To resolve this error, you need to include the sap-language parameter in your request URL. Here’s how you can do it:
  
  
  Modify the Request URL: Ensure that your OData service request includes the sap-language parameter. For example:
  http://<your_sap_system>/sap/opu/odata/sap/<your_service>?sap-language=EN
  Replace <your_sap_system> and <your_service> with your actual SAP system and OData service name. You can set the language code to the desired language (e.g., EN for English, DE for German, etc.).
  
  
  Check Client Configuration: If you are using a client application (like SAP Fiori, Postman, etc.), ensure that it is configured to send the sap-language parameter with every request.
  
  
  Review Gateway Settings: If you are developing or maintaining the OData service, check the service implementation to ensure that it correctly handles the sap-language parameter.
  
  
  Related Information:
  
  SAP Gateway: The SAP Gateway is responsible for enabling the connection between SAP systems and external applications through OData services. Understanding how it processes requests can help in troubleshooting similar issues.
  OData Services: Familiarize yourself with OData service development and consumption, as this will help you understand the importance of various parameters, including sap-language.
  Language Handling in SAP: SAP systems support multiple languages, and the sap-language parameter is a standard way to specify the language for the response. This is particularly important in multi-language environments.
  
  By ensuring that the sap-language parameter is included in your requests, you should be able to resolve the error and receive the expected responses from your OData service.
