If Condition for Text not recognizing column name

[pallavisave7]

I have a text column USERID for which I want to determine part of a USERID based on IF condition. However, I tried as both column and measure, but getting error "can not find column, please use aggregate function". How do I apply aggregate function on text column? I need to work in DirectQuery mode only.

Hi @pallavisave7 
Indeed MAX will not work with text. I am not sure about the expected result but you could try FIRSTNONBLANKVALUE, which is an aggregation that works on text columns and gives (like the name implies) the first value.

I tried 

Known Visitor Id = RIGHT(MAX('Sessions'[Known Visitor Id]),LEN(MAX('Sessions'[Known Visitor Id]) - FIND("\",MAX('Sessions'[Known Visitor Id]))))

However I am getting error:

Hi @pallavisave7 

Try this:

Known Visitor Id =
RIGHT (
    MAX ( 'Sessions'[Known Visitor Id] ),
    LEN ( MAX ( 'Sessions'[Known Visitor Id] ) )
        - FIND ( "\", MAX ( 'Sessions'[Known Visitor Id] ) )
)

If it doesn't work, then please share a sample of your data.

Hi, @pallavisave7 

According to your DAX formula and error message, it seems that the problem occurs because of one missing parenthesis in the function LEN(MAX('Sessions'[Known Visitor Id]):

I suggest you to change the DAX formula like this and check if the problem can disappear:

Known Visitor Id = 

RIGHT(MAX('Sessions'[Known Visitor Id]),LEN(MAX('Sessions'[Known Visitor Id])) - FIND("\",MAX('Sessions'[Known Visitor Id])))

And you can get what you want.

If you still have a problem, you can post some sample data(without sensitive data) and your expected result.

Hi @pallavisave7 

Use MAX(Sessions[column name] in the measure.

Hello @VahidDM,

Thank you for your response, but when I try putting aggreagte function like MAX(Sessions[column name]) I get error 'can not convert value of type text to Number'. 

I need to work in DirectQuery mode only.

 

I believe to apply aggregate function it needs to be numberic data, however my column contains text.
