It is not uncommon to recurrently re-utilize a value created throughout previous data analysis. In this case, would not it be useful to transfer that value into a flow variable and have it available as a parameter inside the workflow from that point on?
That is what the next video explains: how to transform a data cell into a flow variable.
Workflow used in this section can be downloaded from the KNIME EXAMPLES Server under 06_Control_Structures/03_Flow_Variables/04_Extract_Data_for Highest_Sale_Country06_Control_Structures/03_Flow_Variables/04_Extract_Data_for Highest_Sale_Country*
* The link will open the workflow directly in KNIME Analytics Platform (requirements: Windows; KNIME Analytics Platform must be installed with the Installer version 3.2.0 or higher)
