returning multiple dates from multiple rows in a single row

BenMoores — Tue, 07 Jul 2020 06:09:01 GMT

I'm incredibly new to powerBI, only started last week,please be gentle!

I 4 calculated columns, each returning a unique date for a specific ID, it looks like this when I put it into as table:

ID	Date1	Date2	Date3	Date4
1	%DateValue%
1		%DateValue%
1			%DateValue%
1				%DateValue%

It works, but it's very clunky, so I'd like to have it display like this:

ID	Date1	Date2	Date3	Date4
1	%DateValue%	%DateValue%	%DateValue%	%DateValue%
2	%DateValue%	%DateValue%	%DateValue%	%DateValue%
3	%DateValue%	%DateValue%	%DateValue%	%DateValue%
4	%DateValue%	%DateValue%	%DateValue%	%DateValue%

I've been playing around with a few things, importing the data (from CSV) into another table and manipulating it there with relationships on the ID etc. but I just don't understand what's happening there well enough to get this working. Can anyone help?

Hi BenMoores

You can do it easily in Power Query, go to Transform Data > select your table > Home > Group By > set everything as on the screenshot below and click ok.

also, see the attached for reference.

Thanks for the reply Mariusz 🙂 As the data is in calculated columns, I'm not able to bring that into the transform. I'll google and see if there's a way to do this but it seems it might not be possible

Hi BenMoores

Instead of Calculated column, you can create a custom column in Power Query and perform group by ( as explained by Mariusz )

You can read up here ( how to add a custom column in Power BI)
