Calculate value for previous day in matrix

[LFM]

I have a matrix that shows expected exposure for years in the future. On the rows is reportdate and on the columns is the year expectation and values is exposure. Those are in the same table. I want to calculate exposure for the previous day to see how much it have changed from one date to next. How can I do that? I will incude thos values in the matrix. Can I do that with measure or do I have to make a new column?

Hi @LFM ,

Based on your problems, I create a table as you mentioned.

Then I put the table into the Matrix.

Next I create a measure and here is the DAX code.

Measure = 
SUM ( 'Table'[Exposure] )
    - CALCULATE ( SUM ( 'Table'[Exposure] ), PREVIOUSDAY ( 'Table'[Reportdate] ) )

@LFM try the PREVIOUSDAY() function

If you're looking for last date with data, try LASTNONBLANK().
