• What is the cause and solution for SAP error message RSAWBN050 - Connection &1 of type &2 does not exist ?

  The SAP error message RSAWBN050 indicates that a connection of a specified type does not exist. This error typically occurs in the context of SAP BW (Business Warehouse) when trying to access a data source or a connection that has not been properly defined or configured.
  Cause:
  
  Missing Connection: The specified connection (e.g., a database connection, RFC connection, etc.) has not been created in the SAP system.
  Incorrect Connection Type: The connection type specified in the request does not match any existing connections in the system.
  Authorization Issues: The user may not have the necessary authorizations to access the specified connection.
  Configuration Errors: There may be configuration issues in the BW system or the source system that prevent the connection from being recognized.
  
  Solution:
  
  
  Check Connection Configuration:
  
  Go to transaction SM59 (for RFC connections) or DBACOCKPIT (for database connections) and verify that the connection exists and is correctly configured.
  Ensure that the connection type matches what is expected (e.g., if it’s an RFC connection, it should be set up as such).
  
  
  
  Create or Correct the Connection:
  
  If the connection does not exist, create it using the appropriate settings.
  If it exists but is misconfigured, correct the settings (e.g., hostname, port, user credentials).
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the transaction has the necessary authorizations to access the connection. This may involve checking roles and authorizations in transaction PFCG.
  
  
  
  Test the Connection:
  
  Use the "Test Connection" feature in SM59 or DBACOCKPIT to ensure that the connection can be established successfully.
  
  
  
  Check for Transport Issues:
  
  If the connection was recently transported from another system, ensure that all necessary objects and configurations were included in the transport.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SM21) and the application logs (transaction SLG1) for any additional error messages that might provide more context.
