I have some workflows with dependency. I want to wait for the previous workflow done, then continue the next one. I am trying to use the Wait Node, but it seems that it cannot detect file creation/modification/deletion in SharePoint. How can I realize this control to workflows or metanodes? [image]

@cuimaple without a KNIME Business Hub you will face some kind of complexity. That being said I have created a sample workflow that would check the last date a file has been changed on a drive (here simulated using a local folder) - and if there has been a change compared to the last recored date a sub-workflow will be called and the new change date will be recorded in the CSV file.

The main workflow will run every 10 seconds (you can change that to 5 minutes) and will run until you stop it due to a condition loop end that never will be met. [image] The information when the file was last modified will be checked with the help of the Files/Folders Meta Info – KNIME Community Hub - the remote connection (the blue connections) in this case is a local folder so the example can be run in a local environment but they can be substituted for a Sharepoint connection or other remote connection .

@cuimaple maybe you can extract some meta information and compare them to a previously stored record and if the file is newer start your workflow.

The “automation” is a workflow running permanently.
