Dynamic Date and element in Power BI URL

Hi everyone, 

 

Plz help me on this.

 

1. I'm trying to format my URL in the way that it takes 2-3 days prior data

I found out that this code (below) will work for today, but how do I change it 2-3 days before in URL itself?

 

Date = DateTime.ToText((DateTime.LocalNow()), "yyyy-MM-dd"),

 

e.g. Today is 12 Jun, but the data it will show in URL is the latest data avialable, which would be 9 or 10th Jun.

 

So basically i need to create in URL date that would pick up the latest avialable data.

 

 

 

2. In URL some elements would change either number/characteristic. 

Is it possible to create something similar to Pythong, as:

 

for x in range(0,100):
ant then include str(x) into URL, so it will automatically pick up number from 0-100 and relatest to latest date avialable.
 
Thanks alot in advance, any help highly appreciated!

    Mehay ,

     

    Yes, it's like a macro in Excel.

    It keeps all the steps and apply them when the refresh happens.

    Hi Mehay ,

     

    We get this error if the page load is slower than the Power Query request, to fix it, use this code:

     

    let
    Source = Web.BrowserContents("https://www.apple.com/covid19/mobility", [WaitFor = [Timeout = #duration(0,0,0,3)]]),
    Extract = Html.Table(
                            Source, 
                            {
                                {"Link", "#download-card > div.download-button-container > a", each [Attributes][href]}
                            },
                             [RowSelector="#download-card > div.download-button-container"]
                        ){0}[Link],
    GetData = Csv.Document(Web.Contents(Extract),[Delimiter=",",Encoding=65001, QuoteStyle=QuoteStyle.None])
in
    GetData

     

    I just added a timer to delay the load of the page in Power Query.

      Hi Mehay ,

       

      Create this recursive function and run it with current date:

       

       

      (dt as date) as table =>
let
Url =
Web.Contents(
 "https://covid19-static.cdn-apple.com/covid19-mobility-data/2009HotfixDev28/v3/en-us/applemobilitytrends-"&Date.ToText(dt, "yyyy-MM-dd")&".csv"
,[ManualStatusHandling={404}]
),
Result =
if Value.Metadata(Url)[Response.Status] = 404 then
@Query1(Date.AddDays(dt, -1))
else Csv.Document(Url,[Delimiter=",",Encoding=65001, QuoteStyle=QuoteStyle.None])
in
Result

       

      Replace the Query1 reference with the function name.

        Hi camargos88 ,

         

        Indeed Invoked function is a cool one, i do personally like it.

        But in this case it won't make it automized the way i would make it in python let's say.

         

        Moreover., whenever you choose new date of daat to be uploaded, it would open as new Invoked Function every time.

        And that means I need to apply all my filters again and again, os is there a way so function wont create new one but will replace existing with all its filters?

         

        Sorry, im quite new in Power BI, and therefore, not that familiar with M language too.

         

        Thnaks.
