How and why to Unpivot data with Power Query

Рет қаралды 42,553

Күн бұрын

This video showcases 2 examples of when you need to unpivot your data.
The first scenario is a simple unpivotting exercise using just Excel
In the second scenario I use Power BI and work around one of the issues that unpivotting may cause.

Excellent video, thanks so much! I did a Power BI course 2 weeks ago, feel like I've already forgotten nearly everything, plus the data I'm working with is a lot more complex than what we used in the training. Your clear concise video is a lifesaver.

Unpivot is an amazing tool. I like how you’re like “it’s beautiful” because it truly is. Especially the unpivot other columns which gives your source data the ability to expand in columns without messing up your query.

Absolutely!

I had a thorny data problem with some credit card file downloads where I needed different information for different purposes: sales sheet tie out, bank tie out (each neededing horizontal layout with different data filtered) and journal entry (needing no filtering but some cajoling and a vertical layout for entry upload). The unpivot was key. This technique needs to be in everyone's toolkit. As always your explanations are clear and highlights the benefits (and ease) of the technique.

I live that you add the tbl at the start of the table name. Methinks you have a programming background. I do that, too. At first glance, it is seems unnecessary but in complicated vba code it makes perfect sense.

I’ve an accounting background but logical naming just feels right 😀

I’m enjoying your videos so much and happy to keep learning. Thanks for creating great content!🙏 I’m curious to know why use a separate date table as a reference table. Is it essential, or can one go without it? Additionally, for those without Power BI access, is there a way to achieve this in Power Query?

Hi, thanks for the kind comment. They Calendar table allows you to slice and dice one or more Data tables by year month day, financial year, month etc. You can also do this in Excel using Power Pivot ( the pre cursor to Power BI ) kzfaq.info/get/bejne/iLxkatyJnJayfmw.htmlsi=cKLP0tBdKKJNW0mr And kzfaq.info/get/bejne/iLxkatyJnJayfmw.htmlsi=cKLP0tBdKKJNW0mr

7:52 How do you do that? I know how to merge queries with common fields, but splitting a table? The best approach which I can think of is: 1) Duplicate the query; 2) In each respective query, delete the columns which are unneeded. Then you will have two (2) tables, each with the respective columns you need.

@AccessAnalytic Жыл бұрын

I’d reference the queries , remove other columns, and append if more than one source. And remove duplicates.

Great Wyn! The second example was tricky! Thanks for walking through the process. Just curious, I noticed in your Fields list that the My Measures table shows at the top of the list. My field list sorts automatically alphabetically. So, I must name my measures table as something like --myMeasures or 1-myMeasures for it to sort to the top. How did you position yours at the top before the Auditor Table and Calendar table, etc. that would all naturally sort before the M of MyMeaures? I rooted around for a setting and couldn't find one. Curious how you do that. Thanks again for all the tips. Thumbs up!!

@AccessAnalytic 2 жыл бұрын

Cheers Wayne, remove any columns from your measures table and it moves to the top. See the 1:15 mark here kzfaq.info/get/bejne/e8-Hl9140bHLpn0.html

@wayneedmondson1065 2 жыл бұрын

@@AccessAnalytic Thanks Wyn. I think I was trying to sort it to the top of the list before removing the empty column. Also, good to know that a disconnected measures table won't allow for drill-down from a Pivot Table. Thanks again for all the great tips! Thumbs up!!

The tutorial is nice. Calling tidy data in pivot horrible is just 🤣🤣🤣 Tidy data and unpivot data are both perfectly fine, it only depends on what you need it for.

@AccessAnalytic Жыл бұрын

Yep, matrix layout good for reading, horrible for flexible analysis

@tijanameduric Жыл бұрын

in queries yea, in python pivot format, was what we were required to make to analyze. It all depends on what you need, but I agree for a pivot in excel unpivot format is much more useful.

Hi Thanks for the video. I have 3 columns of values and at the very before the column header it is written the date in which identifies the value in the column belongs to a certain date something like this: 202201|202202|202203 how can I fix this issue in power Q to read in Power BI? will it make sense to create 3 different columns of dates relative to the date of the column and then povit them and then povit the 3 columns also? im kindda confuse. your help would be great :)

Do we have to create tables for all dimensions? What if we have many dimensions?

@AccessAnalytic 11 ай бұрын

Yes, pretty much. Certainly all those that have multiple common repeated factors. E.g. date has Year Month Day etc, Product has name, supplier, colour, Customer has address, phone, contact Etc
