Power BI Publish to Web for Anonymous Access is Here

Earlier this week on Wednesday the Microsoft Power BI made an incredibly exciting announcement and released Power BI “publish to web” as a preview feature. This is HUUUUGE news! This was probably the top requested feature and its finally here thanks to the hard work and dedication of the Microsoft Power BI team!

Power BI “publish to web” allows you to easily expose a Power BI report to the world through an iframe that can be embedded wherever you like.

To publish your Power BI report to the web, log into your Power BI site.

Find the report that you want to share and click File in the top left.
Power BI publish to web

You’ll see a message pop up box similar to below. Click the yellow button to create the embed code.

This is where you’ll see a very important warning!
WARNING: Reports that you expose through the “publish to web” feature will be visible to everyone on the internet! This means NO AUTHENTICATION is required to view the report that is embedded in your application.

Once you do that, you’ll receive an embed code that you can then use to expose your Power BI report within your blog as seen below!

As you can see the report maintains all the interactivity features of Power BI. And as your Power BI report updates and changes, those changes will be reflected in your embedded Power BI reports!

Pretty awesome!

MDX NON EMPTY KEYWORD VS NONEMPTY FUNCTION

Non Empty vs NonEmpty

Hey everyone, in this blog I want to address a very common MDX Question. What is the difference between the NON EMPTY keyword and NONEMPTY function? To take it a step further which one should you use?

Non Empty keyword VS NONEMPTY Function.

The big difference between the NON EMPTY keyword and the NONEMPTY function is when the evaluation occurs in the MDX. The NON EMPTY keyword is the last thing that is evaluated, in other words after all axes have been evaluated then the NON EMPTY keyword is executed to remove any empty space from the final result set. The NONEMPTY function is evaluated when the specific axis is evaluated.

Should I use NON EMPTY keyword or NONEMPTY function?

Ok Mitchell, so you told me when each of these are evaluated but really you haven’t told me anything up until this point. Can you tell me which one I should use already? Well, unfortunately, it depends. Let’s walk through an example of each using the BOTTOMCOUNT function.

BOTTOMCOUNT FUNCTION with NON EMPTY Keyword

In this example I’m returning the bottom ten selling products for internet sales. Notice that I have returned all products that have no internet sales, this is not necessarily a bad thing, maybe you want to return products that don’t have sales.

However if you don’t want to return these products then we can try using the NON EMPTY keyword. In the below example you can see the results when I add NON EMPTY to the ROWS axis.

WHOOOAAA, what happened?? A lot of people would have expected the results here to show the bottom ten products that DID have sales. However, that is not the case, remember that I said the NON EMPTY keyword is evaluated LAST after all axes have been evaluated. This means that first the bottom ten selling products which have $0 in sales are first returned and then the NON EMPTY keyword removes all that empty space from the final result.

BOTTOMCOUNT function with NONEMPTY function.

So let’s try this again, if you want to return the bottom ten products that had sales then we must first remove the empty space before using the BottomCount function. Take a look at the code below:

In this code we first remove the empty space before using the BOTTOMCOUNT function. The result is we return the bottom ten products that had internet sales. Once again neither one is right or wrong here it just depends on what you want in your final result.

There is a very common misconception that the NONEM

SSRS Top N and Bottom N Reporting with Duplicates

Previously I wrote a blog on Top N and Bottom N reporting. There were a couple of gotcha I did not cover in that blog so I thought I would cover those here to answer some of the questions I have received. The other blog can be found here.


On a report you are trying to group the top N number of rows together and all others should be in a separate group. Let’s say you want the top 5 sales people based on amount.


In my other blog I showed how to use the Top N and Bottom N filters on groups. The major problem comes in when you have duplicate amounts at the cut off. For example if you want the top 5 sales employees to be in one group based on their sales amount, and three employees tie for the number 5 slot. This would cause more than 5 people to show in the top N group and those same people would show in the bottom N using the technique I showed in the previous blog.


So how do you fix this? You will need a different method to do this. You need to find the cut off amount and spilt the top from the bottom based on that amount.


Here is the table we will use on the report. Notice that positions 4, 5, and 6 have the same amount. If you set the filter on the report to top 5 you will get 6 rows in the top. The Bottom N method I showed in the previous blog will fail because the bottom group will not know about the extra rows in the top group. This will cause row 6 to show in both groups.

Top N Bottom N
 
A better way to do this Top N and Bottom N grouping would be to find the cut off amount and filter the groups based on this.

Here is the main query pulling the data to show on the table.

SELECT        RowNum, Name, Amount
FROM            TopN

 

Now you need to create a new data set and the query will look like below

With O as(
Select top (@N) t.RowNum, t.Amount, t.Name
From TopN t
Order by Amount desc
)
Select Top 1 Amount
From O
Order by Amount

 

I named this dataset MinTopAmount. This query is using a CTE to get the top N amounts. N is a parameter on the report, you can hard code this if desired. Then the outside query gets the lowest amount from that query. This gives you the lowest amount to show in the top N group. This query will only return single row and column with the cut off amount.


Now you need to set up the filters on the groups to filter based on the amount instead of Top or Bottom. These are two adjacent groups on a single table.

Top N Bottom N
 
The Sum of the Amount value form the new dataset, which is named MinTopAmount in this example, should not sum anything because the query only returns one row due to the top 1 in the query with the CTE. The bottom group will have the exact same filter except it will use less than instead of greater than or equal to.


With the N set to 5 it will divide based on the amount at the fifth spot. If there is a tie, it won’t matter.


In this image you can see the bottom group in blue. Notice even though we selected Top 5 we get 6 rows in the top due to the tie, everyone else is in the bottom group.

Top N Bottom N
If you have any issues let me know.
