Global parameters at the start of the workflow

Good day,

Tried to put input parameters to a workflow,  

to ask the global parameters before starting the workflow ,(Modeler type), using a form of input parameters.
This can in KNIME.

Thank you for your help.

If you right-click on a workflow in the KNIME Explorer you can define workflow variables.  These settings will be available throught the workflow.  Alternatively, you can use Quick Form nodes to define these settings and use the flow variables generated from them to configure the rest of your workflow.
