Wrong data from Google Analytics

Hi All,

 

This is my first time to contect to Google Analytics using Power BI Desktop.  I started with something simple by getting only "Users" by date.  However the result I've got loaded to Power BI is totally different from the result I see from Google Analytics web.  

What did I o wrong?  Really confused... @_@@

 

Appreciate advice.

 

Best,

    HI MF_Wong,

     

    I think it may related to api delay, please take a look at following document to know more about this feature.

    Data limits

    Data processing latency

    Processing latency is 24-48 hours. Standard accounts that send more than 200,000 sessions per day to Analytics will result in the reports being refreshed only once a day. This can delay updates to reports and metrics for up to two days. To restore intra-day processing, reduce the number of sessions your account sends to < 200,000 per day.

     

    BTW, you can also contact to google support to get more support.

     

    Regards,

      Hi Xiaoxin,

       

      Thank you for your feedback. 

       

      However i think it may not be related to api delay.  If that's a delay issue, only data of past (few) days will have impact, right?  When I compare the data downloaded from the G.A Web to the data generated via Power BI Desktop for a long period of time (more than one year), none of the data matches. 

       

      = Cube.Transform(#"xxxxxxxx",
              {
                  {Cube.AddAndExpandDimensionColumn, "ga:date", {"ga:date"}, {"Date"}},
                  {Cube.AddMeasureColumn, "New Users", "ga:newUsers"},
                  {Cube.AddMeasureColumn, "Users", "ga:users"}
              })

       

      The above is the code generated from "Add item" step in Power BI Desektop.

       

      Any idea?

       

      Appreciate feedback.

        Hi MF_Wong,

        I just figured this out today. 

        The reason the numbers do not match is due to the sampling limit from google. 

        Here is what I did and worked:

        1- Go to your Query Editor and filter your report using your date field.

        2- Add a custom filter (do not use "Equals..., Before..., After... so on, custome is the only way to prevent sampling). 

        3- Within the custom filter then you can set your filter. I did a range: "is after and equal and is before and equal". I then compared to the same time period on Google Analytics and my data matched!

         

        With the custom filter you are filtering within the cube and not locally on your powerbi desktop so you are able to work around sampling.

         

        Hope this helps,
