Input-Ready Query

Hi Experts,

I created query (Input - Ready Query) on one of my Aggregation level. Now i want to change Key figure value manually and the same value need to appear in my Data Target, but here i am unable to find the save button but the same thing i can do by using RSRT T- code, here i can change the Key figure value and able to save the data and its appear in my Data Target, but why dont i do same in Query Alalyzer. Please guide me.

Thanks - Venkat
