Hello @Jalvear
I’m glad to read that you found the workflow useful. About why the loop end duplicates some columns in your data is something that I can’t evaluate with the information you are providing right now. If you can provide some sampled data, mock data or a picture with the details of the issue, we may be see what’s going on.
About your questions regarding KNIME Server and how to automatize the schedule of a workflow run, or
about which server adapts more to your needs; there are some colleagues in the forum that can provide you some more information.
In the meantime, you can check the following post with some info and ideas about the very same topic.
@bruno29a and @morpheus suggest to do it via batch mode…
Then you may be able to schedule the task by using desktop version as well (?)
