Finally back from Inspire Nashville! What a great conference!
I got a chance today to put together the YXZP for the Field Comparison macro I presented in my session "I WANNA HOLD YOUR HAND... THROUGH HOW (AND WHY) TO BUILD A NESTED MACRO".
The file is attached!
To test it, simply output the "J" output from a join tool and feed it into the macro. The macro will dynamically identify all fields which have different values on the "Left" and "Right" sides of that join, based on the field names coming out of the join (EG Field1 is compared to Right_Field1).
This macro will only work if data types are in the same category.
Let me know if there are any questions or issues getting the macro to work!
