Discount calculation on LC lines

Hi,

I am testing discount function in purchase order where have added 5% discount component in LC along with other landed cost. PO raised with unit cost 100 while taking receipt after applying LC, new discount LC line got created and unit cost in F4105 got updated as 95. What I have noticed that other LC lines are not showing amount as per unit cost 95, there are calculating as per unit cost 100 only. If I have given 5% discount on base OV then LC lines should get calculated on discounted unit cost i.e. 95 where as system is calculating
