How to save a attributes which contain Sub Number array in Process Model?

Question

Hi guys, 
 
 I have a Array out put from Expression Rule: 
 { 
 {1,2,3},{4,5,6},{7,8,9},{10,11,12},{13,14,15} 
 } 
 But I don't know how to save this into Process Property and pass into next node. 
 My next node is a sub process model which will run all elements. 
 for example, this first run of the sub process will be using {1,2,3} 
 
 How can I save this out put into Process Model property? 
 
 Can anyone help me? thanks!

My first suggestion would be to make a CDT where one of the members is (array of integer) type, and have your expression rule output an array of this CDT. Then you could call your subprocess using MNI running once for each item in the CDT.

The type would be "Array of integer" in your new CDT, which is what I was originally trying to suggest.
