Helper IIDisplay first chronological result from Power Query in Power bi without filtering
I have data like this:
That I'd like to incorporate into this table on a dashboard:
Specifically I'd like to create "IRB of Record" which is the first chronological entry per study for IRB_Committee, for each "CIRB" entry. So for instance, this:
In the table on the dashboard, there are several query sources being used, they are all linked by "Protocol_no".
I'm sure I could sort my table by earliest row for each study etc... but I dont want to FILTER because I may need later action dates for other columns.. etc...
Long story short how can I add a column like this without deleting any source data by filtering?
Hi JoeCrozier
You can refer to the following solution.
Sample data
1.Create a rank column in table
Rank = RANKX(FILTER('Table',[PROTOCOL_NO]=EARLIER('Table'[PROTOCOL_NO])&&[Type_]=EARLIER('Table'[Type_])),[ACTION_DATE],,ASC)2.Then create a measure
Measure = CALCULATE(MAX('Table'[IRB_COMMITTEE]),'Table'[Type_]="CIRB",'Table'[Rank]=1,'Table'[PROTOCOL_NO] IN VALUES('Table'[PROTOCOL_NO]),REMOVEFILTERS())Output

JoeCrozierThis worked great! Thank you! I accepted it as a solution but actually I have one question (that I hadnt included originally) thats related and maybe you could help with. So this measure totally returns the correct values, problem is: not every row HAS a value. I.e. not every protocol has a CIRB row. This is expected behavior and I'd love to just show those rows as blank on the dashboard. Problem is, if theres no result in the measure for those rows, they just aren't included on the dashboard. How can i still show the blank row?
That make sense?
