Filter node

You can rename or exclude fields at any point in a flow. For example, as a medical researcher, you may not be concerned about the potassium level (field-level data) of patients (record-level data); therefore, you can filter out the K (potassium) field. This can be done using a separate Filter node or using the Filter tab on an import or output node. The functionality is the same regardless of which node it's accessed from.

• From import nodes, you can rename or filter fields as the data is read in.
• Using a Filter node, you can rename or filter fields at any point in the flow.
• You can use the Filter tab in various nodes to define or edit multiple response sets.
• Finally, you can use a Filter node to map fields from one import node to another.
