Need help on Lookupvalue dax

[Unknown_1]

Hi Team,

I have a dataset of 3 columns a

 

s stated in the picture attached.

I want to do a simple vlookup of the second column in the entire range and want to return the result(Third column) as a new column.

I tried using the simple Lookupvalue dax but was unsuccessful.

Please help me out!

Thank you!

That error is indicating that there are values in Column2 that appear more than once in Column1. If this is the case then LOOKUPVALUE will not work. You will need to decide how you are going to aggregate the data in Column3 and then use the appropriate function (SUM, AVERAGE etc.).

I have cross checked the dataset there is only 1 matching value present in column 2 which is appearing in column 1. However there are a blank row. Is that causing the problem?

Also is there any other way in which I can solve this problem?

Yes, blank rows will also cause that issue with LOOKUPVALUE.
You can try something like...

Calculated Column 2 = 
var _vTable =
SUMMARIZE(
    'Table',
    'Table'[Column1],
    "_value", SUM('Table'[Column3])
)
var _result =
SUMX(
    Filter(_vTable, [Column2] = [Column1]),
    [_value]
)
Return
_result

Let me know how that works.

Using the example table...

Column1	Column2	Column3
AAA-BBB	AAA-BBB	100
ABC-DEF	ABC-FED	50
ABA-AAA	ACA-AAA	75
DAC-FED	DAC-FED	250

You can use a calculated column...

Calculated Column = 
LOOKUPVALUE('Table'[Column3],'Table'[Column1],[Column2])

To get the result...

By doing this it's giving me the error " A table of multiple values was supplied where a single value was expected"
