Flow Variables are parameters used inside a KNIME workflow to dynamically overwrite node settings.
There are many ways to create a flow variable. Each way produces a parameter with different properties. For example, you might want to have a flow variable which is visible throughout the whole workflow or you might want to create a flow variable on the fly with limited scope and visible only within that scope.
Discover the many ways of creating and consuming a flow variable in a workflow.
