Percentage Difference using a Date variable

[Anonymous]

I have a dataset called Call_Trans.

This is a date variable called WeekEnd (this is a week end date of Sunday). I also have a numerical varibale called Transf. 

What I'd like is to have a table where in the Rows will be WeekEnd and column will be Transfers, but I'd also like to show the % difference from the week before.

Thank you for your reply, however this isn't an option to Right-click on the Transfers field in the Values section and select Add Column > % Difference. in my version of powerBI

@Anonymous It's not an option to click and select something, that line means to add a column named "% Difference". Okay leave it, we can create a matrix visual.

Here are the steps to create a table:

1. Open Power BI Desktop and click on “Get Data” to import your dataset.
2. Once your data is loaded, click on “Report” in the left-hand pane.
3. Click on the “Matrix” visual in the “Visualizations” pane.
4. Drag the “WeekEnd” field to the Rows section of the visual.
5. Drag the “Transf” field to the Values section of the visual.
6. To add a column that shows the % difference from the week before, you can use Power BI’s formula feature. Here are the steps to add a column:
   1. Click on “New Measure” in the “Fields” pane.
   2. In the formula bar, enter the following formula: 

Percent Difference = DIVIDE([Transf] - CALCULATE([Transf], PREVIOUSWEEK([WeekEnd])), CALCULATE([Transf], PREVIOUSWEEK([WeekEnd])))​

• Click on “OK”.
• Drag the “Percent Difference” field to the Values section of the visual.

This will give you a table with WeekEnd in rows, Transfers in columns, and a new column that shows the % difference from the week before.

I hope this helps!

To create a table in Power BI with rows representing the WeekEnd dates and columns representing the Transfers, along with the percentage difference from the previous week, you can follow these steps:

1. Create a table visual in Power BI.
2. Place the WeekEnd field in the Rows section of the visual.
3. Place the Transfers field in the Values section of the visual.
4. Right-click on the Transfers field in the Values section and select Add Column > % Difference.
5. In the formula bar, enter the following DAX formula to calculate the percentage difference from the previous week:

% Difference = DIVIDE([Transfers], CALCULATE([Transfers], PREVIOUSWEEK()))

1. Format the % Difference column as a percentage.

By following these steps, you can create a table visual in Power BI that displays WeekEnd dates in rows, Transfers in columns, and the percentage difference from the previous week.
