Required field absent

A field that every row of a table needs has no value: no column is mapped to it, the mapped column is not in the data, or a row leaves it empty. The run stops, at the Map Data node or when Create Scenario saves the rows. Create Scenario also warns, without stopping, about location rows with no id, name or location to identify them.

What to do

In the node's settings panel, map the field to the column that holds it, or rename that column in the source file; the message lists the columns the data has. If a row leaves the value empty, fill it in the source data.
