Re-execute on error

Hello.

I have an issue with a workflow whereby a node may error and needs to be manually re-executed. I believe the error may be caused as I run concurrent nodes with RFC connectors which can’t always connect first time. Whilst one option would be to run each node separately, this would not be the ideal as it would take too long.

Is there a simple method by which I could restart a node which has stopped? This is possible with the Try/Catch nodes but seems overly complicated and I’ve been unable to work out how to implement an infinite Try/Catch loop.

Currently I have a simple program, external to Knime, which presses F7 every 10 seconds to restart the workflow if it has stopped, but this isn’t the most practical solution as it cannot run in the background.

Any help would be greatly appreciated!

Kind regards

David
