dax for week number

[lisaburton]

I want to show the current week only on a matrix of plan vs adherence.

I can display all 52 weeks of the year but i am unsure of how to set up a Dax to only view the current week

Hi @lisaburton ,

According to your description, here's my solution, create a measure.

Check =
IF ( MAX ( 'Table'[Week No] ) = WEEKNUM ( TODAY () ), 1, 0 )

Put the measure in the visual filter and select its value to 1.

After apply filter, get the correct result.

I attach my sample below for your reference.

Can you use the Relative Date Slicer settings to get what you want?

Before that was available, I typically would build into my Date dimension table things like [Months Back] which would be calculated relative to today's date. So if today is in August 2022, then anything in July 2022 would be 1 Month Back, June would be 2, etc. Can you build something like that into your Date dimension for Weeks, then filter on Weeks Back = 0?

Hi Thank you! 

I have tried the slicer but it alters every visual on the report page and I just need it on the 1 matrix 

Do you have the dax forulas for the 2nd option you mentioned?

Try setting the "Edit Interactions" under the Format menu (far left button) that will allow you to make it that the Slicer does, or does not, affect other visuals on the page.

>>Do you have the dax forulas for the 2nd option you mentioned? << I'm more of a SQL guy than DAX, and well, "to a hammer, the whole world is a nail". I used to build Date Dimensions, with all associated properties in T-SQL Views.

Try this:

Weeks Back = DATEDIFF ( NOW(),  [Some Date Column],  WEEK)

I have a 'last week' dax and i can amend this to show the 'next week' date but how do i amend it to show this week date? 

Last Week =

IF (

YEAR ( [Week ] ) = YEAR ( TODAY () )

&& WEEKNUM ( [Week ],2 ) = WEEKNUM ( TODAY () -7 ),

"Yes",

"No"

)
