Calculating Dates across Rows

[amirzoyan]

Hi, 

Dealing with somewhat of an odd problem. The example below, the data gets pulled automatically and the dates for a single report show up in different rows. 

I know how to calculate # of days when the dates are in the same row, but not clear how to do it across rows. Any suggestions? 

Including an image below - trying to figure out how to calculate # of days between the two circled dates.

Hi @amirzoyan,

I created a simple for test.

Please try.

Transform data.

Select all needed columns.

Unpivot Columns.

Select [Attribute] columns.

Pivot Column.

Close and Apply.

Attach the PBIX file for reference. Hope it helps.

Hi, Here is a quick hack which will help you bring all the dates in 1 row and then you can easily find Date Difference. Step 1: Unpivot all the rows = Table.UnpivotOtherColumns(#"Changed Type", {}, "Attribute", "Value") Step 2: Pivot the rows back. It will give you all the dates in single row. = Table.Pivot(#"Unpivoted Columns", List.Distinct(#"Unpivoted Columns"[Attribute]), "Attribute", "Value") Hope it helps Prateek Raina
