Difference Between DAX and calculated column

Hello! 

I’m' trying to figurate the difference between calculate the 'Total sales' in a column and in a measure because the output it's difference.

This is mi data:

But. When I do the measure I don't have the same result. I notice that it's a common problem but i didn't figure how to solve it (Filter? Related? which function?)

So. This is my dax formula:

Thanks!
