What is this code doing and is there a way to display the result without typing in Power Query

[Anonymous]

Hello everyone, i have a question. I am taking over a project from another developer and i dont quite understand what is this code doing even after referring to the https://docs.microsoft.com/en-us/powerquery-m/date-functions

Therefore, I also want to find out is there a way to display this result without typing into the power query editor. Thanks. 

#"Filtered Rows3" = Table.SelectRows(#"Filtered Rows1", each [Transaction Date] <= Date.EndOfWeek(Date.AddWeeks(Date.From(DateTime.LocalNow()), -1))),

@Anonymous , filter data a week before

Date.From(DateTime.LocalNow()) // today date 

Date.AddWeeks(Date.From(DateTime.LocalNow()), -1) // a week before date

end of last week

Date.EndOfWeek(Date.AddWeeks(Date.From(DateTime.LocalNow()), -1))

so filtering date before last week end date.

You can do that dax, but you can create a flag column or a new tbale

Monday last week end date

Week End date = [Transaction Date]+ 7-1*WEEKDAY([Transaction Date],2) -7

Sunday last week end date

Week End date = [Transaction Date]+ 7-1*WEEKDAY([Transaction Date],1) -7

a new column

if([Transaction Date] <= [Week End date],1,0)

Thanks for the explanation.

Is there a way where can i can show the result visually instead of keying them into the power query? Thanks!

@Anonymous , not very clear, You can have last week end date in dax like

Monday last week end date

Week End date = [Transaction Date]+ 7-1*WEEKDAY([Transaction Date],2) -7

Sunday last week end date

Week End date = [Transaction Date]+ 7-1*WEEKDAY([Transaction Date],1) -7

power query like

Date.EndOfWeek(Date.AddWeeks(Date.From(DateTime.LocalNow()), -1)

what you mean by visually ?

Hi @Anonymous,

In fact, these values aren't static values strings and they are dynamic calculation results based on M query/DAX functions. You cannot directly typing function string in the filter panel.

Understood, Thanks!

Hi @Anonymous,

I'm glad to hear this helps. 🙂

BTW, power bi can only extract text values from this input panel so all the inputted 'characters' or 'function names' will be forced escapes /recognized as text values. That is the reason we had to do custom with the filter function itself instead of operating on the 'quick action' panel.
