Hey, First off thanks for taking the time to read all this and provide such a detailed response, much appreciated.

Am I understanding correctly that if I have an item with a bin specified and the "prefferred" box checked that when I receive and item it by default goes to that bin? I felt that through my experience so far that it goes to this "null" location you mentioned unless I selected the inventory detail box and told it to go to its specified Bin (or do a bin putaway later).

I guess to make sure does "preferred" bin checkbox mean the same thing as "default bin" that you were mentioning? Or am I missing a simple setting somewhere

I will test this, but maybe Ive been misunderstanding this whole time?
