Compare two tables and only show delta

[gheyman]

I have two tables

User_CostSourceData
User_PBoM3A

They both have a common field: Part Number

I need a query that will show me where there are deltas between the two (if one part number is on one but not the other). Any suggestions for an efficient query?

Thanks

Create an anti join query in Power Query.
