Definitely appreciate this opportunity to use the Optimization tool. I turned the workflow for 1 item into a macro and fed it the list of values for output 2.
My second output involving all of the specific boxes per batch are not in the same order as listed, but for the amounts and weights are the same per Number of items.
I've integrated, futhermore, a workflow which calculate all combinaisons to have a max weight of 15 kg, and the best combinaison to maximise the revenue.
