Tableau 计算字段 - 分类

Question

Hi I am a Tableau beginner and need some help.

I have a sheet that looks like this.

ID    Type
27    A
      B
38    B
19    A
      B
28    A
      B
18    A
29    A
      B

For an ID, if the type is A and B, I want to classify it as A. So desired result is this.

ID    Type
27    A
38    B
19    A
28    A
18    A
29    A

I can't just say 'if type = A and B then A' because there are some other fields involved in where I need to both to show.

I need to a calculated field that will allow me to tie this condition to the ID field specifically.

One way you could do this is with an LOD calculation. Something like this should do the trick:

IF {FIXED [ID] : MAX([Type] = "A")}
AND {FIXED [ID] : MAX([Type] = "B")}
THEN "A"
ELSE [Type]
END
