Hey @mtwilliamson
I find iterative macros a little tricky to debug - so what I do is build them as regular old Alteryx flows first - and instead of Macro Inputs, I use a regular input tool bringing in data from "Input.yxdb", and for the macro outputs I'll have the iterator leg overwriting "Input.yxdb", and the results leg going to a browse tool.
This way - you can simulate the behaviour of an iterative macro - every time you run it, it's as if you've done one additional iteration in the macro.
(Alteryx doesn't offer any way natively to debug iteration 2 onwards of an iterative macro - so this is the only real way to simulate it)
