Sum by categories (Table)

Hi Folks!

I stopped against the next wall, let's see if any good soul can help me!

As you can see in the picture, I have a TABLE with the next columns:

- Production Order No_ -> From Table 1

- Sample No_ -> From Table 1

- Cantidad Muestra -> Is a measure, and the original field is in Table 2

What I'm trying to do is to sum the field "Cantidad Muestra" by "Sample No_".

I have tried the next formula/Measure, without success:

Cantidad Muestra TRY = CALCULATE( [Cantidad Muestra]; ALLEXCEPT(Table1;Table1[Sample No_]))

The thing is, I need the data to  be shown without using slicers, as shown in the picture.

Any ideas?

THANK YOU!
