Days Between

Hi amandabus21 ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data.  

(2) We can create  measures. 

Days = 
var _max=CALCULATE(MAX('Table'[Delivery Date]),FILTER(ALL('Table'),'Table'[Purchase Orders]=MAX('Table'[Purchase Orders])))
return DATEDIFF(TODAY(),_max,DAY)

Abs Days = 
var _max=CALCULATE(MAX('Table'[Delivery Date]),FILTER(ALL('Table'),'Table'[Purchase Orders]=MAX('Table'[Purchase Orders])))
return ABS(DATEDIFF(_max,TODAY(),DAY))

(3) Then the result is as follows.

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,

Neeko Tang
