Field matches several columns

Automatic detection found more than one column that could hold a field, because their headers differ only in case or spacing, such as revenue and Revenue. They may hold different values, so none is read and the run stops at the Map Data node.

What to do

In the node's settings panel, map the field to the column that holds it, or rename the other columns in the source file so that only one matches.
