PO Receive: Save as "In Transit" - Consequences?

PO Receive: Save as "In Transit" - Consequences?

My bookkeeper brought to my attention that the new default for saving a purchase receive is to "Save as In Transit".



I realize that one can use the arrow to save as received, but I'm wondering:

a) What does this new option mean? When would one use it, and what are the bookkeeping and inventory consequences of marking inventory as "in transit"?

b) Why is this the new default?

Any info would be appreciated!
