Using messages in the KNIME Console within the Workflow as user information

[taylorpeter55]

Hi all,

I have built a workflow that runs through a loop to download data from various sources (incl SAP downloader node) . However, there may be times when a user does not have the relevant access to a source or has input the wrong input parameters.

To handle these instances, I have built-in Try/Catch logic so that the workflow continues running if an error is encountered (as we have circa 60 sources to pull from).

However, to ensure optimum visibility for the user I would like to display the error message seen on the node (and in the KNIME console) as a message in the final Excel output (so that the user is aware of which items are missing).

Please can anyone advise whether what i am trying to achieve is possible? And if so, which nodes do i need to add to my workflow to achieve it?

Thanks in advance.

You want to write down only errors or all messages? If errors only then you can use Try/Catch sequences on multiple places in workflow and write down error in database together with some additional info like timestamp, part of workflow where it failed… I did something similar when building ETL process with KNIME.
