DAX formula to compare 2 rows

Anonymous — Tue, 14 Jul 2020 11:36:53 GMT

Hi,

I have a table like the below and want to setup a calculated column with DAX to check whether each key from the "Concat" column has a value or not.

For example:

- po1drop1 has 2 rows, with 1 row has Value=100, so I want the Result=Yes

- podrop2 has 1 row only with blank value, so I want the Result=No

- podrop3 has 2 rows, with 1 row has Value=100, so I want the Result=Yes

- podrop4 has 2 rows, with 1 row has Value=100, so I want the Result=Yes

- podrop5 has 1 row only with blank value, so I want the Result=No

- podrop6 has 1 row only with blank value, so I want the Result=No

Not sure how to put the FILTER or EARLIER function in place in order to achieve the desired result.

Can anyone assist? Thanks.

Best regards,

Emily

Anonymous , Try a new column

if(sumx(filter(table,[concat]=earlier([concat])),[Value])=100 ,"Yes","No")

if(maxx(filter(table,[concat]=earlier([concat])),[Value])=100 ,"Yes","No")

Hi Anonymous ,

You can create a calculated column using DAX as follows:

IfExists = var cnt = CALCULATE(DISTINCTCOUNTNOBLANK(Category[Value]), FILTER(Category, Category[Category] = EARLIER(Category[Category]))) return IF(cnt > 0, "Yes", "No")

It will give you following result:

In the above DAX, just use columns from your original data. I did this on a test data at my end.

Thanks,

Pragati11 Thanks, I just tested your result in my file but I got the entire column with "Yes".....not sure if I did something wrong in the formula?

Hi Anonymous ,

What's the datatype of your "VALUE" column? Is it wholenumber or text?

Thanks,

Pragati11 VALUE column is a STRING data type and some rows with blank data.

Sorry that I found out your proposed solution is not 100% working in my real enviroment, because the Value column is a string type rather than numerical type so I can't use SUMX or MAXX fuction.

Any other way to get the same result in considering the Value column is a string?

Emily

Anonymous , Maxx will work for String. Do you want sum up value to check?'if it have only numeric that you can try [Value]*1

Hi Anonymous ,

Not sure why it is not working at your end.

I have tried the same formula when VALUE column is a string or numeric, it works for me.

Can you check again as the DISTINCTCOUNTNOBLANK will work both for String and numeric columns?

Thanks,
