01 - Missing Values Example

This workflow shows how KNIME deals with Missing Values.

We replace them based on data type for the column PO Date and for a specific column where we use the Mean Value for the quantities.

This workflow goes along with my weekly newsletter aboud data analytics called "The Data Alchemist", click on the link below to find out more or subscribe for free.
