What's the DAX syntax equivalent to a sql windowing
Hi Nathaniel_C
Lots of work indeed ! Thanks a whole lot for digging into this !
I'll be trying it out today and will let you know how it flies.
I will indeed have to publish it on the PBI Service so I'll tell you how it works too.
Thanks again & have a great day,
Franck
Hi again Nathaniel_C
I will indeed need to use a date slicer in my report as users will need to look into Statuses including in the past.
What would be the syntax then to be able to use a slicer ? Should I just replace
max(GetDate[ParameterDate])
in the DAX query by
MAX(GetDate(Calendar[Date]))
where Calendar is my Date Dimension Table Name ?
I'll keep fiddling in all this in the meantime...😉
Thanks a bunch for your much appreciated help !

Hi franck_axires ,
How is the fiddling going?
So if you use ALLSELECTED() from the slicer, (I created a new VAR to play with this, and not affect the rest of the code. However the way the Slicer works, it also filters all the dates in your table. So to solve that, I went back to Power Query and used your date column to create a new date table, which allows us to use it as a slicer, but not affect your original table. Works as expected. Try it!
I have to work on something else for awhile, but the one thing I want to research is keeping the new table current as you update your base table. I know there is a way to do it, just have to find it.
If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
NathanielConcatenate ContainerID =VAR SelectedDate = ALLSELECTED(PositionDate[Date]) //PositionDate is the new table with just one column.VAR StatusCode1 = CALCULATE(max(Positions[StatusCode]),Filter(Positions,(Positions[PositionDate])=SelectedDate))//what is the StatusCode for this datereturn CALCULATE(CONCATENATEX(Positions,Positions[ContainerId], ", "),Positions[StatusCode]=StatusCode1,Filter(Positions, Positions[PositionDate]<=SelectedDate))//use the StatusCode and the Selected Parameter Date to return the ContainerID)) Hi Nathaniel_C
Thanks a lot for your input.
I'm fiddling all the way...😜
Power BI is throwing an error in the CONCATENATEX & COUNTROWS formulas saying it cannot compare a date format to a string.
I have Datetime data on both sides of the = or <= operators and MAX doesn't implicitly convert data to strings so I'm a bit puzzled.
But I'll keep digging and let you know how it all went...!
Thanks again and have fun on your upcoming project !
By the way, why do you concatenate ContainerIds in your first formula ?

Go back into PQ and check your new table. You may have to change data type.

"By the way, why do you concatenate ContainerIds in your first formula ?"
You said originally,
"I need to find all the ContainerIds with a StatusCode of SUBL up to a certain date. "
Is that not what you were looking to find?

Hi franck_axires ,
Plug this in and apply to a card.
How many Status Code = CALCULATE(COUNTROWS(Positions),FILTER(Positions,Positions[PositionDate]=ALLSELECTED(PositionDate[Date])))Select 10/4/2018Are two codes on one date expected?If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos are nice too.
Nathaniel Hi Nathaniel,
Thanks again for the energy you put in solving this problem.
The solution you offered didn't work in the end.
The actual solution resorted to manipulating the filter context with a series of treatas statements.
I'll publish a blog post about it and link to it here.
Thanks again !
