Filter cannot be read

A product cell of a lanes or unit conversions row is written as a filter, such as "Chilled" in product.tags, and the filter cannot be read: it is not an expression, names an attribute a product does not have, or compares a value of the wrong kind. A row whose products are unknown cannot be applied, so Create Scenario does not save the scenario, and Network Optimization stops on such a scenario.

What to do

Correct the filter on the rows the message names, as the message says. A filter on products reads product.name, product.tags and the other product columns; text is written in quotes.

Where it comes from

Shown by Center of Gravity, Consolidate Shipments, Create Scenario, XYZ Segmentation. It is one of the messages about the scenario.
