If I understand correctly, the use of the Function Node should be avoided as it uses many resources.

What is the correct way to Set a Flow without using a Function Node?

I thought it could be done by using a Change Node, however when I tried it didn't work.

I tried using the Rule Set msg.payload to flow.DailyPumpTest.  
The message payload is coming from a Dashboard dropdown.  
Currently the output message from the Change Node is "undefined".

Try the other way round. Set (the) flow.DailyPumpTest **TO** (the value of) msg.payload

Yes, that will do it. Makes me look a bit silly.

Thank you for you timely help 🙂
