Create a Purchase Order with multiple items - Create Single PO with multiple items listed from array

Welcome to the Make community!

Your “Retrieve Data” trigger module is already outputting multiple bundles.

You should not need an Iterator module there since the result is NOT an array.

Iterators are only used for arrays.

Every result (item/record) from a search module will output a bundle. To “combine” them into a single structure, you’ll need to use an aggregator of some sort.

Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and has applies to many use-cases.

Set the Source module of your iterator to your Trigger module.
