dax function

[s_kula]

Hello, I need to write a formula in dax that will calculate a date from a list of dates from a table. The formulas are supposed to take into account the product id filter:
1. the first function is to calculate the maximum date, maximum -1, maximum -2 so that I can choose the appropriate string value
2. the second function is to return a specific value from the row with the calculated date and product id, e.g. quantity.

I guess I failed to check I have a list of dates.
In this list, the maximum date is 24/04/2023.
However, I want to be able to calculate the next e.g.
22/04/2023 (max-1) and another 17/04/2023 (max-2), i.e. subsequent dates in a decreasing sequence. The function must include a filter for a specific product id.

At the same time, the result of this function is supposed to be a filter to find other values ​​from a table row.
e.g.
date 22/04.2023 for product id 25, is to be a filter to the sales quantity for a given date and product id.
