Query in flexible planning

Dear experts, I have a doubt in flexible planning, i have created a info structure with 2 aggregate information in my planning type "Planned value" and "Actual value". In MC94 i have updated the requirement qty for the material for "Planned value" as 300 ea. When i transfer the demand in MC90, the requirement qty is displayed as 150 Ea. I am unable why the requirement qty of 300 ea is getting changed to 150 Ea. How this value is of 150 Ea is calculated
