Field help (ALLTYP1) 

The allocation type for an order line has as its default value the allocation type defined in the order header. It is however possible to modify the allocation type (Global/Detailed) in the line on the condition that the selected order transaction authorises it. A global allocation is carried out as a function of the total stock available. A detailed allocation reserved the stock objects (Lot - Serial number - Status - Location).

If the order line is allocated, this information is no longer accessible.
