Power BI：过滤预测版本

Question

I am in a bit of a puzzle here and hope you guys can help: I have the following table showing our forecast version:

Our forecast process works in the following way: On the first day, each month, we get a new "SOP Version" and "LAG 1". After some days the "latest" LAG-version changes from "LAG 1" to "LAG 0" for the rest of the month.

Example in table: Latest "SOP Version"=SOP5. From "day 1" to fx. "day 4" the table will be loaded with "LAG 1" only. On "day 5" the table will be enriched with "LAG 0".

Now, what I want to make is a dynamic (global) filter, which always filters the latest "SOP" and "LAG"-version on the Power BI report I have.

I have managed to make a summarized table in Power BI filtering the "lowest" LAG value for each SOP-version:

SOP&LAG (Latest Vers) = SUMMARIZE('Forecast';'Forecast'[SOP Version];"LAG (lowest value)";MINX('Forecast';'Forecast'[LAG]))

But I can't figure out to isolate the the latest SOP Version (SOP5) with its latest LAG-version (LAG0). I am not even sure this is the right approach? All ideas will be greatly appreciated. Thanks. Br, Jakob

I think you can filter your table with TOPN() like this:

TOPN(1;SOPLAG;SOPLAG[SOP Version];DESC;[SOP Version];ASC)
