Helper IIICreate new measure to compare values from two dates
Hi all,
I have a table such as :
| Reporting date | ID Project | Status | # houses | RP date |
| 31-12-20 | Volt | MS_Prep | 24 | 07-07-24 |
| 31-12-20 | Miroi | MS_AvProj | 137 | 25-06-23 |
| 31-12-20 | PAS II | Chantier | 100 | 24-03-25 |
| 31-12-20 | Navez | En attente/bloqué | 64 | 12-12-22 |
| 30-06-21 | Volt | MS_Prep | 18 | 07-07-24 |
| 30-06-21 | Miroi | MS_AvProj | 137 | 30-08-23 |
| 30-06-21 | PAS II | Chantier | 100 | 20-12-25 |
| 30-06-21 | Navez | Chantier | 75 | 12-12-22 |
| 30-06-21 | Luttr | MS_Prep | 100 | 10-05-25 |
I would like to create several measures would allow me to compare data from the latest date (here 30-06-2021, but il will change over the time) to the previous one (here 31-12-2020). I need to display :
- List of new projects (in the example : Luttr)
- List of projects that changed status (here : Navez)
- List of projects that changed # houses (here : Volt & Navez)
- List of projects that changed RP date (here : Miroi & PAS II)
I guess I need to use an if statement but I can't figure how to specify "compare each project based on the date. Take in account only the latest date & the previous one".
thanks in advance for your help!

Hi, AFra
This took me some time, but I got the results.
Create the following measures:
the Date:_LastDate = VAR _top1 = TOPN ( 1, ALL ( 'Table' ), [Reporting date], DESC ) RETURN MAXX ( _top1, [Reporting date] )_previousDate = VAR _t = FILTER ( ALL ( 'Table' ), 'Table'[Reporting date] < [_LastDate] ) VAR _preProject = TOPN ( 1, _t, [Reporting date], DESC ) VAR _preDate = SUMMARIZE ( _preProject, [Reporting date] ) RETURN MAXX ( _preDate, [Reporting date] ) // MAXX(FILTER(ALL('Table'),'Table'[Reporting date]<MAX('Table'[Reporting date])),[Reporting date])NewProject:
_NewProject = VAR _preProject = SUMMARIZE ( FILTER ( ALL ( 'Table' ), 'Table'[Reporting date] = [_previousDate] ), 'Table'[ID Project] ) VAR _if = IF ( MAX ( 'Table'[Reporting date] ) = [_LastDate], IF ( MAX ( 'Table'[ID Project] ) IN _preProject, BLANK (), 1 ) ) RETURN _ifHouse, RP date, Status:
just change the distinctount field_ChangeStatus = VAR _count = SUMMARIZE ( FILTER ( ALL ( 'Table' ), 'Table'[Reporting date] >= [_previousDate] ), [ID Project], "Count", DISTINCTCOUNT ( 'Table'[Status ] ) ) VAR _Change = FILTER ( _count, [Count] > 1 ) VAR _Project = SUMMARIZE ( _Change, [ID Project] ) VAR _if = IF ( MAX ( 'Table'[Reporting date] ) = [_LastDate], IF ( MAX ( 'Table'[ID Project] ) IN _Project, 1, BLANK () ) ) RETURN _ifResult:

AFra , Create measures like
project Not having same status =
var _max = maxx(allselected(Table),Table[RP date])
var _max = minx(filter(allselected(Table),Table[RP date] <_max),Table[RP date])var _maxs = calculate(Max(Table[Status]), filter(Table, Table[RP date] = _max)) //use allselected(Table) , if needed
var _mins =calculate(Max(Table[Status]), filter(Table, Table[RP date] = _max)) //use allselected(Table) , if needed
return
countx(values(Table[Project]), if(_maxs<> _minx ,[Project], blank()))
New Project =
var _max = maxx(allselected(Table),Table[RP date])
var _max = minx(filter(allselected(Table),Table[RP date] <_max),Table[RP date])var _maxs = calculate(count(Table[Status]), filter(Table, Table[RP date] = _max))//use allselected(Table) , if needed
var _mins =calculate(count(Table[Status]), filter(Table, Table[RP date] = _max))//use allselected(Table) , if needed
return
countx(values(Table[Project]), if(isblank(_mins) && not(isblank(_maxs)) ,[Project], blank()))The last two need to have the same approach like formula one

Hello amitchandak,
thank you for your suggestion, but it doesnt seem to work : it does not retrieve the right lists.
Here's the full data if you - or anyone else - are in the mood for help : ) link to data
