Hi @chrisdane,

as a first reply to your issue.

I followed the exercise in the ESM-Tools workshop (https://github.com/esm-tools/workshops/blob/main/202207_AWI_ESM-Tools/exercises/7.5_workflow_manager.md see the solution).

And this worked for me as a first try:

flow:
    workflow:
        next_run_triggered_by: tidy
 
        subjobs:
            my_new_subjob:
                batch_or_shell: batch
                order_in_cluster: concurrent
                run_on_queue: ${computer.partitions.pp.name}
                nproc: 1
                run_after: tidy
                script_dir: "/work/ab0995/a270089/myrunscripts/"
                script: "hallowelt.sh"
                submit_to_batch_system: True

I placed this in a runscript as a new component. What also worked is to put everything starting from workflow in another component, as you mentioned in your issue. I also do not understand why this needs to be in a component.
I also had the same questions about the keywords as you mentioned. I agree that this needs to be improved in the documentation with some more examples.

If you have any other suggestions for the workflow manager, please also add them as a comment to the following discussion #1023. Thank you.

This issue cannot yet be closed.

I also do not understand why this needs to be in a component.

Maybe we can change this in the future, so that it doesn't have to be in a component. More on that when we resume the work on the workflow manager.
