Table to get the hierarchy

Hi,

I am using AII to attach packaging hierarchy to OUTBOUND Delivery. I need to find out the packaging hierarchy which is linked to a particular document.  I know, I can get this information from COCKPIT, but I need to send this information to external system.

Can anyplease please tell me in which table in AII will I get the packaging Hierarchy.

I have done the following:

1. Get the Document GUID from DM_DOC table for Document ID

2. Get the Object IDs from DM_DOC_OQCC table.

3. Get the hierarchy from DM_Object table.

Problem: I am not getting Unit level IDs in DM_DOC_OQCC table i.e. I am getting Pallet,Case and Bundle level information in this table but not unit level. Hence, i am unable to retrieve the entire hierarchy.

Thanks,

Madhav
