Table Value Comparison

Hi All,

 

I would like to compare the values of a column (same data) from 2 different tables and flag the unique values in a conditional column in the dataset so they can be filtered out.

 

Basically this is an example of what I am looking to do.

 

Table1.ColumnProject

12345

12346

12347

12348

 

Table2.ColumnProject

12345

12346

12347

12348

12349

12350

 

So the unique values in Table 2 (12349 & 12350) would be flagged as "New Projects" in a conditional column, and the reset would be "Existing Projects"

 

Can this be easily done?

 

Thanks.

Hi @Sime ,

 

You can create a custom column in table 2 with below code:-

column =
VAR result =
    CALCULATE (
        FIRSTNONBLANK ( '__Table 1'[ColumnProject], 1 ),
        FILTER (
            ALL ( '__Table 1' ),
            '__Table 1'[ColumnProject] = '__Table 2'[ColumnProject]
        )
    )
RETURN
    IF ( ISBLANK ( result ), "Existing Project", "new project" )

 

Thanks,

Samarth

Hi @freginier,

 

Thank you for your response.  I am unable to get the solution you have posted above to work in my scenario as the 3rd argument appears to not accept the second table and [column] when creating the measure.

Any ideas where I am going wrong?

 

Ideally if I could perform this cross table comparison in the data set and add a calulated column that would be ideal.
