According to the Oracle Inventory Management Cloud User Guide, material status control is a feature

that allows users to restrict transactions for certain items or lots based on their status. A material

status can be defined with different transaction types that are allowed or disallowed for items or lots

with that status. If intransit shipment transactions are not available under transactions allowed on

the edit material status page for active material status, it means that the intransit shipment

transaction type is not enabled for status control (D). The active material status usage being set to

sub inventory (A) or lot © does not affect the availability of intransit shipment transactions under

transactions allowed. The intransit shipment transaction type having a start date or not (B) does not

affect the availability of intransit shipment transactions under transactions allowed.
