Hello everyone,

i'm just a beginner and have a few problems with aimms. 

I am investigating a warehouse in which customer orders are split up into partial orders. Each partial order is assigned to a zone.

My problem is that Aimms assigns the partial orders to multiple zones instead of just one.

In the attachement you can see that a partial order is assigned to several zones. 

j are the partial orders; z are the zones

Is there a way to say in a constraint that only one value can be assigned?

Thank you!!!
