We recently connected to NetSuite using ODBC so we can navigate tables and query the database. I'm having difficulty determining how NS calculates inventory levels though.

I noticed the table "Item_Location_Map" has quantity on hand which seems accurate, but I don't see a way to specify at what point in time. I figured maybe it calculates real time based on all transactional data but ran into another issue. All the details for a transaction are on the Transactions table and Tranaction_Lines except for...oddly enough...the quantity.

If I look up a say invoices and pull in the quantity field, it is always empty. Some invoices have a quantity_packed or quantity_picked value but that doesn't really help. I found "Inventory_Numbers" has quantities but only for transactions that use inventory details.
