Impact of Incremental Dataset refresh partitions on the Power Query AddRankColumn function....

I have a table of records that contains date and time of record creations.

I wanted to rank records by date and time.

I used the Power Query AddRankColumn

It worked fine in PowerBI Desktop.

However I soon understood that I wasn't getting the expected ranking in PowerBI Service because I implemented Incremental Refresh on my dataset.

Basically what I observed was that records were Ranked within each partitions created by PowerBI Service.... Leading to completely useless and inaccurate my rank column.

How would you suggest to ensure the ranking applies across partitions?

The reason I am doing that initiallly,  is that I wanted to filter the report with the last 2 or 3 extractions, so selecting rank 2 or 3, shall have addressed that.

Update: I have actually used the DAX Rank function instead, which gives me what I want....

nevertheless, the partionning impact on the PowerQUery is still interesting to be aware off.
