Formula for adding yesterday's date in a new column in Power Query in Excel and Power BI

[lbrown]

I need to add a new column that shows yesterday's date. The formula I have to calculate today's date is:

Date.From(DateTime.FixedLocalNow())

This new column shows me today's date, but I need the column to show yesterday's date. I tried the following combination and I am receiving Error in each cell.

Date.From(DateTime.FixedLocalNow()) -1

@lbrown,

you can use the Date.AddDays() function: 

Date.AddDays(Date.From(DateTime.FixedLocalNow()),-1)

Thanks it worked.

Update: I added the new column in Power Query Editor and I went back to my dashboard tab to Refresh the Pivot Charts but they are all blank now and I have to rebuild them. Do you know how I can fix this?

Hi @lbrown,

Can you share the file? How did you create the chart? Maybe the old charts use the date "Today" while you change it into "Yesterday".

Is there a way we can put a text tag saying "Yes/No" instead of the actual date @v-jiascu-msft @lbrown

Hi @v-jiascu-msft

Unfortunately I'm not able to share the spreadsheet because the data is confidential to my company. I loaded the data table to the Data Model and created the pivot tables based on the workbook's Data Model. The pivot charts were created from the pivot tables. The pivot tables and charts don't currently use a reference to the new data column, but when I added the new column and pressed refresh all they are simply going blank when I refresh.

Hi @lbrown,

Can you build a dummy one? Sorry, I can't give more suggestions without the data model.

Hi Dale,

I rebuilt the Excel Sheet in Power BI and I have no problems updating the charts after I add new columns. This error may be an Excel issue, but thank you for your assistance.

Best,
