Dear,
To make it simpler, Lets break it in two steps.
1. Calculate a factor by dividing :=Divide(100,000,Calulate(Sum(Table, Value),Filter(Product=ProductA),Datesbetween(Date,StardDate,Enddate))
for example outcome is 450%
2. Then Calulate(Sum(Table, Value),Filter(Product=ProductA),Datesbetween(Date,StardDate,Enddate))*450%
That I tried but ended up 100,000 from top to bottom all rows.
