I can't seem to set an event for an item change

SOLVED

I am trying to get an event trigger when an item quantity changes so I can perform a real time update in a UI.  I have tried setting Post Write Events on IM_ItemWarehouse and IM_ItemTransactionHistory, but although I can see the DB Tables changing/updating I am not getting and events from Sage.  Does anyone know if there is a table that I can set events on for item changes ( WH transfers, item Adjustments, SO invoiced, ... )?
