Ship date for a Sales Order line

Hi All,

I want to find the ship date for a sales order line. but did not find the corresponding column

to get the information when the line have been shipped.

I actually want to find out ship date for the sales Order line.

ACTUAL_SHIPMENT_DATE      -- OE_ORDER_LINES_ALL

CONFIRM_DATE                        -- WSH_DELIVERY_DETAILS

ULTIMATE_DROPOFF_DATE    -- WSH_DELIVERY_DETAILS

INITIAL_PICKUP_DATE             -- WSH_DELIVERY_DETAILS

which column to be consider?

Thanks in advance.
