Structuring Pre-aggregated Data
Hi,
I'm wondering whether anyone can help me as I'm quite stuck.
I don't have direct access to my data source for use in Power BI, so my data is pre-aggregated before I import it. My data contains a multiple different tables with the same categories for example:
Measure 1:
| Month | Department1 | Department2 | Total |
| Feb-24 | 254 | 562 | 816 |
| Jan-24 | 201 | 487 | 688 |
| Dec-23 | 225 | 421 | 646 |
| Nov-23 | 284 | 500 | 784 |
| Oct-23 | 178 | 497 | 675 |
Measure 2:
| Month | Department1 | Department2 | Total |
| Feb-24 | 181 | 441 | 622 |
| Jan-24 | 224 | 543 | 767 |
| Dec-23 | 258 | 429 | 687 |
| Nov-23 | 232 | 497 | 729 |
| Oct-23 | 193 | 552 | 745 |
How can I structure this data so that I can use Department 1, 2 and Total as series in visuals and filters in a slicer, as well as being able to use the date in a slicer. I've so far only been able to the sum of the departments to a visual without them being individual series.
Apologies if this is very basic and straightforward.
Many thanks.
Hi rock_cloud ,
According to your description, you can use the unpivot function in power query. The exact steps are:
1. Click Transform data to open the power query interface
2. Select the Department1 Department2 columns, right click and select the unpivot columns option.At this time there will be a total, department name and department id for the columns of the table
So you can filter by date, department name or total.

Hi,
In the Query Editor,
- Remove the total column from each table
- Append all the tables
- Select the first column, right click and select "Unpivot Other Columns"
Hope this helps.
Many thanks for these solutions! Worked perfectly and saved a massive headache! 👍
