Distinct elements related to another column

Hello,

 

I have the following table:

 

| A  | B  |
|----|----|
| A1 | M1 |
| A1 | M2 |
| A2 | M5 |
| A2 | M3 |
| A2 | M1 |
| A2 | M3 |
| A3 | M7 |
| A3 | M1 |

 

 

I need to find the distinct elements on the column 'A' and to create another column with the first element of the column 'B' found for the element in 'A'. The result will be something like this:

 

 

| A  | B  |
|----|----|
| A1 | M1 |
| A2 | M5 |
| A3 | M7 |

 

I've already tried several ways but I don't know how to obtain the final result...

Hi @capko 
In the power query view, choose remove duplicate under rows, and this should do it. or use distinct ( as a measure or calculated column)

I need to do it using DAX. I started like this:

 

Test=
VAR A = SUMMARIZE(Table;Table[A])
RETURN A

 

 

But with this I only can return a table with distinct elements

Measure =
 var _A = DISTINCT('Table'[A])
         return
         _A
    

It wont work as requested because the output wont be the same as the one shown in m first post
