Oh man. I was actually writing a script to send a downstock alert for an item to our warehouse team. So, say if Bin A is preferred in Location A for an item & Bin A has less than 10 Available units, so my script was searching if there is at least 1 On Hand in other non-preferred bins for the same location for the item. One of my colleagues is actually surprised that we have to write a script for the downstock alert ; that NetSuite does not do it out of the box already.
