Group Grids to Meet Threshold Macro error

[RachelJ]

Using the awesome Make Fractal Grid macro and the iterative Group Grids to Make Threshold macro with the goal of splitting locations into grids with as close to 60 locations as possible without the grids exceeding a set size.

Make Fractal: https://gallery.alteryx.com/#!app/Make-Fractal-Grids/5d12d139826fd313ccaa70e9

Group Grids: https://gallery.alteryx.com/#!app/Group-Grids-To-Meet-Threshold/5d024b908a9337071c109b62

I've used these macros before with no issue, but now the Group Grids macro is throwing an error: "Iteration #1: Combination (22): Tool #3: The anchor (name=Input) does not allow more than 1 incoming connection." 

The macro runs fine on it's own, but when placed in a workflow it errors. I've tracked back through the macros to the tools in the error message and and am at a loss for why/how that error is being generated. Workflow is attached. 

What am I missing?

Hi @RachelJ ,

I think the workflow is struggling to work properly with the AMP engine turned on. Probably there are tools in the macro that don't support multi-threaded processing? (can't vouch for that, it's mostly speculation)

Anyways, I turned off the AMP engine and it ran fine for me in less than 19 secs

Cheers,

Angelos

@AngelosPachis Ahhh! Of course. That did the trick. Thank you so much for your help!
