SSAS MDX: Alias for a Measure Name

Standard

I was working on a requirement that needed me to write MDX code that had an alias for a measure name. If it was SQL, you could just do something like select [column name] as [new column name] from [table name] but in MDX it’s not straight forward. What you could do though is declare members in your MDX statement. so to alias a measure name & your code would look something like:

[code type=”sql”]

with member [measures].[new name] as [measures].[old name]
select
{[measures].[new name]} ON COLUMNS,
{[Date].[Calendar Hierarchy].[ALL]} ON ROWS
FROM [Cube Name]
[/code]

if you’re executing MDX code using OpenQuery, then you’ve one other option, something like this would work:

[code type=”sql”]

Select "[measures].[old name]" as "[measures].[new name]" from openquery(ConnectionName,’select {[measures].[old name]} ON COLUMNS from [cube name]’)

[/code]

Note: After taking inputs from business, Naming should be taken care in the cube. My requirement was to pull data from multiple cubes & so I was aliasing it so that I could standardize the names across different cubes.

I hope this gives you a good starting to alias names while writing MDX code.

Questions Power Users Ask about Excel: #1 of N

Standard

In this series, I intend to document common questions asked by Power users about Excel connected to SSAS cubes (or data warehouse) after they go beyond the basic stage of understanding & using Row labels, column labels, report filter & values in Pivot Tables. This post is #1 of N:

a. How to Sort Data?

There are two ways to do this & here they are:

#1: Select a cell that has a measure value > Right click > Sort > sort the values in ascending or descending from here:

sorting Excel ad hoc report ssas cube

#2: Alternatively, you can also do the same thing by: Select a value from the filed that needs sorting > go to Home Tab > Sort & Filter > from here you should be able to sort data in ascending for descending order:

b. How to add slicers?

They might not know what slicers are but I’ve been asked how can I add filters where users can see the filter values before picking the value. I’ve also been asked by a Power user for the capability for adding “global filters” who had couple of pivot tables in a single sheet. They also come in handy if you’re building Excel Dashboards. With that, here are the steps:

1. Based on your requirements, decide if multiple items on a dashboard (excel sheet) need to be affected with one click

2. Now, for the purpose of this blog post, let’s assume that you have two Pivot Tables like shown below:

two excel reports slicer 1

Note: the Two Excel Pivot Tables are created by connecting to same cube. And the slicer comes from the same cube.

3. And what if you need to slice data in both pivot tables by one common slicer? Let’s say we want to slice the data in the two pivot tables that we have by Product Category – here’s what you do (assuming that the tables are related in your data source and slicing makes sense)

4. click on any of the pivot table and you’ll see PivotChart Tools in the toolbar

5. Switch to Analyze Tab & click on insert slicer & Select the field that you want as slicer & click OK

pivot table insert slicers

6. you’ll see a slicer on your sheet now:

slicer on pivot tables

7. Let’s format the report to make it look better:

#1: move the slicer such that it does not overlap any of the pivot tables.

#2: In this case, I want to move the slicer to the top of the sheet and change the slicer to have 5 columns. Here’s how you can do that:

select the slicer > from the toolbar > slicer tools > column

slicer tools option excel

#3 I also changed the slicer style from the slicer tools to match its color palette with that of the Pivot Tables:

8. Note that the slicer is connected to just ONE pivot table. Let’s connect it to both pivot tables

9. From Slicer Tools options > Pivot Table connections > check all pivot tables that you want the slicer to be connected to:

pivot table connections excel

10. Done! Test your slicers, with one click you should be able to see that the data gets sliced in both pivot tables:

#1: Sliced by Bikes

excel pivot analysis data 1

#2: Sliced by Accessories

excel pivot analysis data 2

c. How to change the layout of the Pivot Tables?

Without formatting and changing the layout, the excel pivot table looked like this:

step 1 excel pivot table from power pivot

Now, let’s work step by step to meet the requirement:

Step 1: click somewhere on the Pivot Table and from the Toolbar, Switch to the Design Tab under PivotTable Tools

Pivot Table Tools Design Excel

Step 2: Now here, Go to Report Layout > Show in Tabular Form

Pivot Table Layout Tabular Form

Step 3: As you might have noticed the “hierarchical” structure is now broken up into multiple structure getting us closer to meet the requirement.

half way pivot table layout

Step 4: In our requirement, you can see that it does not give the user to see the “+” or “-” (expand, collapse) buttons. So, let’s hide these buttons from the report from Step #3

Right click somewhere on the pivot table > PivotTable Options > Display tab > uncheck the box that says “Show expand/collapse buttons“:

pivot table hide expand collapse button

Step 5: so now it looks as follows:

excel pivot table power pivot

To recap, Here’s what we had to do: Change the Layout of the Pivot Table & we also hid the expand/collapse buttons too.

Conclusion:

In part #1 of N, we saw:

1) How to sort data?

2) How to add slicers?

3) How to change Pivot Table layout?

Remove Duplicates in Excel Tables using Data Explorer Add-in:

Standard

In this blog post, we’ll see how you can remove duplicated and clean data in excel tables using Data Explorer Add-in.

Problem:

Our Excel Table has following Data:

Month Month Name
1 January
1 January
1 January
2 February
2 February
3 March

And we want to remove duplicates to make the data-set look like this:

Month Month Name
1 January
2 February
3 March

 

In real world data-sets, we wouldn’t have few rows but lot’s of rows and doing it manually wouldn’t be the wisest option. With that in mind, let’s look for a few-clicks solution that can help us remove duplicates.

Solution:

If you haven’t already, download the Data Explorer add-in preview available for Excel 2010 & 2013. It can do a lot more than removing duplicates – it’s a great add-in and it’ll save you lots of time especially if your job involves discovering, cleaning and combining data for analysis purposes. After you’re done installing the add-in, use the steps below to remove duplicates in an excel column:

1. Open Data in Excel. Switch to Data Explorer Tab

2. For the purpose of the demo, I am assuming that you already have the data in excel file. If not, you can connect to other sources via the add-in.

3. Data Explorer add-in > Excel Data> From Table

Excel: How to split the content of one excel cell into separate columns?

Standard

I wanted to explore a data-set in excel. I thought I would do that using Excel. The problem was that when I opened the data-set, data was in one column. It was “supposed” to be in different columns but no – I found that it was in one excel cell. This was not Excels fault – it was just the way the data-set was defined. Here’s what I mean:

open a data set in excel text to columns

Can you see that the TWO values are in ONE column?

Problem? Yes. How do we solve it? Turns out there’s a nice feature called “Text to Columns” that should be of help here. Let’s try that:

1) Excel Toolbar > Data > Data Tools > Text to columns

excel text to columns data tools

2) This should open the “convert text to columns wizard”

Step 1: I chose Delimited

Step 2: I chose Comma as the delimiter.

Here are other delimiters that you could choose:

split an excel columns tab semicolon comma space user defined

Step 3: I left the default choices. But you could change the data format if you want. You could also choose the destination cells.

Clicked on FINISH

3) Nice! Here’s what I wanted – And I added a header row.

And my data exploration:

Conclusion:

In this blog-post, we saw how one can split excel cell into separate columns at each comma, tab, space, semicolon or user-defined-character.
