Yes/no value not readable

A column mapped to a yes/no field holds a value other than TRUE or FALSE. Words such as yes, x or 1 mean true to some sources and something else to others, so none of them is read as either, and the run stops at the Map Data node.

What to do

On the row the message names, write TRUE or FALSE in the source data. If the wrong column is mapped to the field, map the right one.

Where it comes from
