Rank in direct query mode

[Anonymous]

Hi,

How would I go about ranking values in direct query mode.  The DAX function RANK does not seem to work.

Any help appreciated

TIA

I faced this a couple of months ago

two ways to do this, you can create a Measure using rankx 

this means that when you slice your data, your rankings get recalculated

another option is to do the rank within the SQL select query

this means your ranking remains the same regardless of how you slice your data

this will show you how to do it the SQL way: http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=109028

Thank you so much for your reply. I tried the RANKX way but I got an error saying the RankX function is not supported under direct query model. How did you solve it? By rankx or SQL ? 

[ukeasyproj]

go to file->options and settings -> options

under direct query, select "allow unrestricted measures"

That's a right way to do it. However, all DAX functions are only allowed to apply in measures. I want to add each serial number 's rank as a new column as by comparing their timestamp and then focus on test data from the same rank, like how many failures do I got on the first run. I don't really think I could handle that with one single measure.

Did you work it out?

Looks like it is not supported . It should get added as a feature
