• What is the cause and solution for SAP error message CM_EHFND_COMN100 - No key was passed to the application. ?

  The SAP error message CM_EHFND_COMN100 with the description "No key was passed to the application" typically occurs in the context of SAP applications that require a key or identifier to process a request. This error can arise in various scenarios, particularly when dealing with APIs, OData services, or when trying to access specific business objects without providing the necessary key.
  Causes:
  
  Missing Key Parameter: The most common cause is that the application or service call is missing a required key parameter. This could be due to incorrect configuration or a programming error.
  Incorrect URL or Request Format: If you are making an HTTP request (e.g., to an OData service), the URL might be incorrectly formatted, leading to the absence of the key.
  Authorization Issues: Sometimes, the user may not have the necessary permissions to access the data, which can lead to the application not being able to retrieve the key.
  Data Model Issues: If the underlying data model has changed (e.g., fields have been removed or renamed), it may lead to this error if the application is not updated accordingly.
  
  Solutions:
  
  
  Check the Request: Ensure that the request being made to the application includes all required parameters, especially the key. If you are using an OData service, verify that the key is included in the URL.
  
  Example: For an OData service, the URL should look something like /EntitySet(KeyValue).
  
  
  
  Review API Documentation: If you are using an API, refer to the API documentation to confirm the required parameters and their formats.
  
  
  Debugging: If you have access to the backend, consider debugging the application to see where the key is expected and why it is not being passed.
  
  
  Check Authorization: Ensure that the user has the necessary permissions to access the data. This may involve checking roles and authorizations in the SAP system.
  
  
  Consult with Developers: If you are not the developer, it may be helpful to consult with the development team to ensure that the application logic is correctly implemented and that all necessary keys are being passed.
