Move Inventory Request lost functionality

In 10.1.400, the Move Inventory Request form auto-selects a “To Bin” value after inputting a part number. It no longer does this in All we can find is that the combo boxes for the “From Warehouse” and “To Warehouse” are now using Erp:BO:PartWhseSearch for its EpiBOName under the EpiCombo section, while 10.1 uses Erp:BO:WarehseSearch.

Switching back to Erp:BO:WarehseSearch does not fix the issue.

Has anybody run into this?

You have primary bins set on that part/site?
