Does anyone know of a way to impart any restrictions to the Reallocate Items page without purely removing the role permission? We place sales orders into pick for a few days but as far as NS is aware a sales order is still pending fulfullment until the pick is complete. In an ideal world we would like to stop items being reallocated if on an order with a specific flag or at least add an approval process to reallocating

Why don't you just start the item fulfillment and leave them in picked state?

we can have orders committed with stock that we don't want to immediatly be sent for pick
