## Calculate consecutive decreases over time?

Hi, hopefully someone can help with this? I have a table that looks like the below

 Client_ID Year Month Tickets_Created 1044 2019 Jul 92 1044 2019 Aug 65 1044 2019 Sep 33 1044 2019 Oct 12 1044 2019 Nov 10 1044 2019 Dec 2

What I want to do is analyze Client_IDs who have a consecutive Tickets_Created on a month by month basis.  To do this I created a calculated column which compared the current month to the previous month

 Client_ID Year Month Tickets_Created Difference 1044 2019 Jul 92 -2 1044 2019 Aug 65 -27 1044 2019 Sep 33 -32 1044 2019 Oct 12 -20 1044 2019 Nov 10 -2 1044 2019 Dec 2 -8

Now what I want is using the above, get a table that shows the top ten Client_IDs that have the most consecutive months decrease in tickets. So for example, the above Client_ID would have a consecutive decrease of 6 months. If the same Client_ID had an increase this month (compared to November) then they would no longer show on the top 10 table as this would reset the conescutive months they have decreased.

I hope this makes sense? Appreciate any help

Hi, @JD09631

I have spend some time together with experts using some random sample. We found that you can make the consecutive count, but the tricky part is you have to re-count each time when there is increase in the tickets.

I am afraid that DAX do not support this kind of calculation, maybe try with power query.

This is my consecutive count formula if needed:

``````Count concecutive decrease =
IF (
[Differece] < 0,
CALCULATE (
COUNTROWS ( 'Table' ),
FILTER ( ALLEXCEPT ( 'Table', 'Table'[Client_ID] ), [Differece] < 0 ),
'Table'[Month] <= EARLIER ( 'Table'[Month] )
) + 0,
BLANK ()
)``````
