• What is the cause and solution for SAP error message /IWBEP/SBDM090 - Data source reference node must not be intial ?

  The SAP error message /IWBEP/SBDM090 indicates that a data source reference node is not initialized, which typically occurs in the context of SAP Gateway or OData services. This error can arise when there is an issue with the configuration or implementation of the OData service, particularly when the service is trying to access a data source that has not been properly defined or initialized.
  Causes:
  
  Uninitialized Data Source: The data source reference node is not set up correctly in the service implementation.
  Incorrect Mapping: The mapping between the OData service and the underlying data model may be incorrect or incomplete.
  Service Implementation Issues: There may be issues in the implementation of the service methods (e.g., GET, POST, etc.) that are supposed to handle the data source.
  Model Configuration: The data model might not be properly configured in the service definition.
  Authorization Issues: Lack of proper authorizations to access the data source can also lead to this error.
  
  Solutions:
  
  
  Check Data Source Initialization: Ensure that the data source reference node is properly initialized in your service implementation. This may involve checking the code in the relevant methods (e.g., GET_ENTITY, GET_ENTITYSET).
  
  
  Review Service Implementation: Go through the implementation of your OData service to ensure that all necessary data sources are correctly defined and initialized. Look for any missing or incorrect logic that might prevent the data source from being set.
  
  
  Validate Model Configuration: Check the service definition and ensure that the data model is correctly configured. This includes verifying that all entities and associations are properly defined.
  
  
  Debugging: Use debugging tools to trace the execution of the service and identify where the data source is not being initialized. This can help pinpoint the exact location of the issue.
  
  
  Check Authorizations: Ensure that the user executing the service has the necessary authorizations to access the data source.
  
  
  Rebuild the Service: If changes have been made to the data model or service implementation, consider regenerating the service and reactivating it to ensure that all changes are applied.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for additional insights or similar issues encountered by other users.
