Getting value which is second highest date through date relationship table

[TotunG]

Hi,

I have a main data table which has a relationship with a reference date table that is used to 'slice' values to compare them in a waterfall chart.

I essentially need a measure to give me the Value of the second highest date value but within the filter context of the Month slicer that is also active on the page. 

So without filter context, second highest date is: 01/11/23 and therefore value of 4. But I want this to be applied within filter context so say if  Month 12 is not included in the slicer, 2nd highest date would be 3 (01/03/23 - 22). 

There is a relationship between these below tables and the slicer is based on the Month column of the Date table.

Main Data:

Date	Value
01/11/23	5
01/12/23	4
01/03/23	2
01/03/22	1

Month / Date Table:

Month	Date
11	01/11/23
12	01/12/23
3	01/03/23
3	01/03/22

Hi @TotunG ,

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

(1) My test data is the same as yours.

(2) We can create two measures. 

rank = RANKX(ALLSELECTED('Main Data'),'Main Data'[Date],MAX('Main Data'[Date]),DESC,Dense)

second highest date value = CALCULATE(MAX('Main Data'[Value]),FILTER(ALLSELECTED('Main Data'),'Main Data'[rank]=2))

(3) Then the result is as follows.

Thank you for your input, although I think its a bit more complex due to the relationship of the date table that I dont think you cover. 

This Sample PBI might explain it better:

Hi @TotunG ,

The two tables in your pbix file do not have any date columns, please check your pbix file.
