How to create a column with the currently valid value and the value valid in the previous month

[mtrevisiol]

Hi everyone,

I have a table thar contains, for each product, the corresponding price list with the validity start date and the validity end date:

My goal is to create two columns:

- The first one, CurrentPrice, contains the currently valid price, which is €0,509 for the first product and €4,295 for the second one. Both prices have ValidityEndingDate = 31/12/1799, which means that the price is valid indefinitely;

- The second one, PreviousPrice, contains the price that was valid in the previous month (January 2022), which is (again) €0,509 for the first product and €4,277 for the second one.

Do you know how I can create the two columns? I think I should use ALLEXCEPT to calculate the values for each product, but I don't know how to compare dates to get what I want.

Here is the PBIX file: https://www.dropbox.com/s/he1q3z2s5n9jvss/Price%20Lists.pbix?dl=0

Thank you!

Change that weird 1799/12/31 to a reasonable date such as 2099/12/31,

Excel worksheet formula is already powerful enough,

@CNENFRNL unfortunately there's a problem. The second measure returns the second most recent price, but my intent is to get the price that was valid one month ago (January 2022), at least for most days of the month, and not only the previous price. I hope I've explained myself.

That's great, thank you!
