Calculate Payment Date minus Billed Date

[jonnyA]

I work for a Medical Billing Company and I have been asked to create a formula on how long it takes a claim to be paid from Billed Date to Paid Date.

I'd assume the formula is Paid Date minus Billed Date, but I do not know how to write that formula in Power BI.  I tried quick measure, however, that did not work.

Count of Payment_Date minus Count of Billed_Date =

COUNTA('vw_Demo_Payments_Dataset_BP'[Payment_Date]) - COUNTA('vw_Demo_Payments_Dataset_BP'[Billed_Date]).

Any suggestions on how I can make my formula work?

Thanks in advance!

Payment Date minus Billed Date = datediff(selectedvalue(Dataset_Payments_Dataset_BP[Billed_Date]),selectedvalue(Dataset_Payments_Dataset_BP[Payment_Date]), day )

You can use the DATEDIFF function! See documentation below. 

https://learn.microsoft.com/en-us/dax/datediff-function-dax

More specifically, click new measure instead of quick measure. Then use:

DATEDIFF('vw_Demo_Payments_Dataset_BP'[Payment_Date],'vw_Demo_Payments_Dataset_BP'[Billed_Date],DAY)

If this works for you, please mark as a solution!
