Aggregate column not in input

An Aggregate node groups by or summarizes a column that its input does not have. Without it the result cannot be computed, so the run stops at the node. A dashboard tile or scenario query that names a missing column is refused the same way.

What to do

In the node's settings panel, choose a column the input has; the message lists them and suggests a close match where there is one. If the column should exist, check the earlier step that is meant to produce it.

Where it comes from
