• What is the cause and solution for SAP error message /BDL/TASKMANAGER068 - RFC connection 'NONE' was already registered in SDCCN ?

  The SAP error message /BDL/TASKMANAGER068 RFC connection 'NONE' was already registered in SDCCN typically indicates that there is an issue with the registration of an RFC connection in the SAP system, specifically in the context of the SAP Data Consistency Check (SDCCN) framework.
  Cause:
  
  Duplicate Registration: The error usually occurs when there is an attempt to register an RFC connection that has already been registered. This can happen if the system is trying to register the same connection multiple times, possibly due to a misconfiguration or a previous failed registration attempt.
  Configuration Issues: There may be issues with the configuration of the RFC destination or the SDCCN settings.
  System State: The system might be in a state where it is trying to re-register connections that are already active or registered.
  
  Solution:
  
  
  Check Existing Registrations:
  
  Go to transaction SDCCN and check the list of registered RFC connections. Look for the connection 'NONE' and see if it is already listed.
  If it is listed, you may need to remove or deactivate it if it is not needed.
  
  
  
  Remove Duplicate Entries:
  
  If you find that the RFC connection 'NONE' is already registered, you can try to remove it from the SDCCN settings. This can often resolve the conflict.
  
  
  
  Review Configuration:
  
  Check the configuration of the RFC destination in transaction SM59. Ensure that the settings are correct and that there are no duplicate entries.
  Verify that the connection parameters are set correctly and that there are no issues with the network or connectivity.
  
  
  
  Restart the Task Manager:
  
  Sometimes, simply restarting the task manager or the relevant background jobs can help clear up any temporary issues.
