Show fields in one table of two tables

[MetLife]

Hi,

I have two tables that share a common column called "PolicyNumber". How do I create a query that shows fields for rows where PolicyNumber is in table#1 but not in table#2?

Thanks,

I used Ctrl T to convert tables to Excel tables and then wrote 1 formula as shown.

Use the query wizard.
That has an Unmatched query.
