Solved: PowerQuery: Filter Top N

ovetteabejuela · ‎11-23-2017

In Power Query, is there an equivalent function to filter top N items.

What I'm trying to do is filter on the latest 7 days and they don;t have to be consecutive days - just the latest 7 days available in the records.

How can this be done?

HI @ovetteabejuela,

You can refer to below steps to filter the dynamic last 7 days:

1. Add custom steps to find out the last date from current table.

Custom1 = List.Max(#"Changed Type"[Date])

2. Enable date filter on date column and use above variable as the parameter.

#"Filtered Rows" = Table.SelectRows(#"Changed Type", each [Date] >= Date.AddDays(List.Max(#"Changed Type"[Date]),-7))

you can create a column using rank function and then filter on this new column
