This workflow here demos how you can generate a report pdf and automatically save it on the disk, or send it via email. We do this by using the Call Local Workflow node, which is part of the extension, Personal Productivity Tools. The same can be accomplished with the Call Remote Workflow node, which then executes a workflow on a KNIME Server. Note: Remember to check that the (file) extension in both the Call Local Workflow (Row Based) and Binary Objects to Files nodes is the same.
