Hi
I need to create a measure (and it has to be a measure, not a column, due wider reports/ calculations/ interdependencies). I need that measure to return the Ref which relates to the first start date. In the event that the first start date occurs twice or more, I need it to return the first occurrence.
Example data is below:
Ref | Start Date |
123456 | 01/01/2021 |
789123 | 03/04/2021 |
456019 | 09/05/2021 |
839213 | 12/05/2021 |
127459 | 01/01/2021 |
293022 | 27/02/2021 |
934859 | 13/02/2021 |
294850 | 15/04/2021 |
930573 | 18/04/2021 |
2938502 | 29/05/2021 |
754392 | 23/03/2021 |
So, from my data above, the first start date is 01/01/21 - that occurs with refs 123456 and 127459, so I'd want the answer to be 123456.
I can obviously get a measure which lists the first start date using Min, but beyond that I'm hitting a wall.
Would be very grateful for any advice.
Thanks
Solved! Go to Solution.
@JamesCarter try this meaure
Top Ref = CALCULATE ( MIN ( Ref[Ref] ), TOPN ( 1, ALLSELECTED ( Ref ), Ref[Start Date], ASC ) )

Hi,
Try these measures
First date = MIN(Data[Start Date])
Measure = FIRSTNONBLANK ( TOPN ( 1, VALUES (Data[Ref]), [First date],ASC ), 1 )
Drag the second measure to a card visual. The result will be 123456.

Actually ignore that bit about variable.
I thought it had worked, but it hadn't - so I've reverted to what you did and that remains perfect.
Thanks again

Thanks Ashish,
Absolute superstar. That worked a treat.
I tweaked slightly to make the first measure a variable and I'm absolutely getting the result.
Brilliant stuff - very grateful. I'd been playing with FIRSTNONBLANK, MIN and TOPN but just couldn't get it - haven't used ASC before. That's a new string to the bow!
Thanks again
You are welcome.

Hi @parry2k
I really should properly wait to investigate before replying - lesson for the future.
I've found what I did wrong in the previous attempt and yes, absolutely, your solution worked.
Thanks again
Hi @parry2k
Thanks so much for responding and for your proposal.
I couldn't quite get it to work (it wouldn't let me call the start date). Sure it's something I did wrong in translating the measure to my actual table.
Happily @Ashish_Mathur 's solution worked, but I'm really grateful for your time and offer of help.
I do love the support people offer on these forums.
Thanks again
James
