I think there maybe a Netsuite issue. We are having strange behaviour with Bin Transfers since this morning. I have logged this with Netsuite and they attached it to a defect.
I filed the Support case as well, they did give me an alternate solution "Alternate Solution: Use Inventory Adjustment transaction instead."
Biomerics_Admin - Thanks for the heads up!!! We had actually used the Inventory Adjustment for a critical shipment going out today. Not the most efficient way to change status, but not a terrible solution.
