Populating the value once when there is duplicate.

[Sudharsanan]

Hi friends,

I need some help in achieving the below using DAX. Table 1 is with Unique ID and table 2 is with duplicated ID, so i want to pull the value from Table 1 where i need to populate the value only once when there is duplicate ID's.

Table 1

ID	Value
A	2
B	4
C	5
D	6
E	7
F	9

Table 2

ID	Value
A	2
B	4
B
C	5
D	6

Thanks in Advance

IDK if i would do that with dax, I would just do it in the power query editor, and remove duplicates.

Is there a particular reason you would want a blank value with a duplicate ID?

Im not sure im understanding what you want, but if I had to guess...

Your wanting to Pull the value for B in Table 2 Since it has a duplicate ID (B) in it?

So your end result would be 4?

Or what is your expected output supposed to look like?

@eTribble Thanks for the quick turn

Yes you are right. When i have a duplicate id i need to have the value for first id and the remaing should be blank.

this is my expected result

ID	Value
A	2
B	4
B
C	5
D	6
