If Condition for Text not recognizing column name
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, Anonymous
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 Anonymous
Use MAX(Sessions[column name] in the measure.

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.
Hi Anonymous
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.
