Not allocated in CKMLCP

Dear sap Gurus,

I have small doubt in CKMLCP ,last month I did ckmlcp at multilevel price determination system showing “Not Allocated”.

For exp: FG stock 2 Qty within 2qty I sold-out 1qty .if we run multilevel price determination system rollup price dIff roll-up from

lower level to higher level. And system check how much is stock available and how much stock Consumption.  in my case

price diff sharing to available stock 1 qty and  remain price diff showing “not allocated “

please check my screen shot .
