Aii - Free Pack to Delivery Order

I am trying to use the mobile transaction to FreePack a Delivery Order. I have assigned the document to the mobile device. I have entered the High level pack item and lower level pack items. Upon saving the pack I see the heirarchy is created and the items are in stock. I do not see any association that the items were associated to the document or delivery order. The document status does not change. Is this proper behavior. How do I get the dock status to change and the items to be associated with the Delivery Order
