Today() function DAX unfiltering my visual table

[Jtbonner1986]

Hi, 

I have a table in my report that summerises a runing stock total. 

I use a measure that find the lastest date which the stock levels fall below 0 - per material. 

This all works fine. However, i then want to calculate the number of months between the date above and todays date. 

When i add a measure with Today() in this completely unfilters all the filters than have been applied to the table in the first place. 

Below 

Visual Table 

Material ID	Date of First Neg Stock	01/01/2024	01/02/2024	01/03/2024
123	01/03/2024	100	50	-10
456	01/01/2024	-100	200	400
789	01/02/2024	50	-150	300

Date Of First Neg Stock =  FIRSTNONBLANK ( 'LineOfBalance'[Date], IF ( [EndingBalance] < 0, 1) )

When I add a measure thaty includes Today() i then see all other material IDs that have previously been filtered (correctly) 

so i am wodering how i can get my measure to calculate between [Date Of First Neg Stock] and Todays date? 

Many thanks,

Josh

Hi @Jtbonner1986 ,

You can create a new measure.

Months Since First Neg Stock = 
VAR CurrentDate = TODAY()
RETURN
IF (
    NOT ISBLANK([Date Of First Neg Stock]),
    DATEDIFF([Date Of First Neg Stock], CurrentDate, MONTH),
    BLANK()
)

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

Best Regards,
