DAX Beginner - How to get last date & no.of days

Anonymous — Fri, 23 Dec 2022 04:57:48 GMT

Hello, I am a beginner in DAX, need help with the below problem:

Goal is to achieve the last date & no.of field columns. Last date is nothing but the attendance date of that store employee that he worked and how many days has it been from today to his/her last date.

Remember: Store supervisor, store employee# are in one dimension and date is coming from another calendar dimension table.

In which table is it best to create dax for this ??

Expected results should be like this:

Last Date

No.of days

10-Jun-2020

926 days

15-Jun-2020

921 days

Below is the sample data:

Store Supervisor	Store Employee	Employee#	Attendance Date	Last date	no.of days= last date to today
Braden	Brad	3425	16-Jan-20
Braden	Brad	3425	19-Jan-20
Braden	Brad	3425	10-Jun-20	10-Jun-2020	926 days
Jessica	Messi	9879	24-Feb-20
Jessica	Messi	9879	16-May-20
Jessica	Messi	9879	15-Jun-20	15-Jun-2020	921 days

Hi,

I do not know how your datamodel looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file.

I hope the below can provide some ideas on how to create a solution for your datamodel.

Last date measure: = IF ( HASONEVALUE ( Employee[Store Employee] ), MAXX ( RELATEDTABLE ( Data ), Data[Attendance Date] ) )

Number of days measure: = IF ( NOT ISBLANK ( [Last date measure:] ), INT ( TODAY () - [Last date measure:] ) )

Note : You can use

datediff(FirstDate(table[Date]),'LastDate'[Last date],DAY)
