For example, if you flatten an array port with 10 string elements, the output returns 10 string ports. If you flatten a 3-dimensional array, the output returns a 2-dimensional array.

A table contains a string port Name and an array port Phones. You want to flatten the array port. The table contains the following values:

Name	Phones
Adams	[205-128-6478, 722-515-2889, 650-213-4020]
Jane	[650-321-4506]

When you flatten the array port, the output is as follows:

Name	Phones	GCID_Phones
Adams	205-128-6478	1
Adams	722-515-2889	2
Adams	650-213-4020	3
Jane	650-321-4506	1

You can edit the Occurs value of a flattened field to extract a specific number of elements in the array. The value must be a positive integer greater than 1. The value determines the number of elements to extract. For example, you can change the value of Occurs to 2 to extract the first two elements of the array. The output is as follows:

Name	Phones	GCID_Phones
Adams	205-128-6478	1
Adams	722-515-2889	2
Jane	650-321-4506	1
