Look up value within a table

I’m trying to create a column that looks up the value in another row within a table. This is what my data looks like:

Question Number

Username

Answered

Timepoint

1

ID1

2

A

1

ID1

4

B

1

ID1

6

C

2

ID2

3

A

2

ID2

4

B

2

ID2

7

C

 

What I need is for a new column called Answered_A that pulls in the Answered value at timepoint A for each Unsername. It should look like this:

Question Number

Username

Answered

Timepoint

Timepoint_A

1

ID1

2

A

2

1

ID1

4

B

2

1

ID1

6

C

2

2

ID2

3

A

3

2

ID2

4

B

3

2

ID2

7

C

3

 

I’ve tried merging the table with itself, but I end up with all the values from Answered in the new column. I've also tried Lookupvalue but I can't get it to work.

 

Is there a DAX code that will do this?

Please try this DAX calculated column expression

 

Timepoint A =
CALCULATE (
    MIN ( Table[Answered] ),
    ALLEXCEPT ( Table, Table[Question Number], Table[User Name] ),
    Table[Timepoint] = "A"
)
