% Change in a non contiguous Matrix

[Fcoatis]

I have this matrix with measure Tot Gross = sum(INVEST[Gross Bal]) . How do I calculate the percentual difference of Tot Gross (being calendar non contiguous due to holidays and weekends)?

Hi @Fcoatis,

What's the mean of the percentual difference of Tot Gross, could you please post an example? 

The difference includes increase and decrease between the two numbers you are comparing.

Increase = (New Number - Original Number)÷ Original Number × 100.

Decrease = (Original Number - New Number)÷ Original Number × 100.

In your requirement, what's the New Number and Original Number?

Hi Angelina,

I'm looking for a measure that calculates (actual value/previous value)-1

Hi @Fcoatis,

You can use a measure, please review the following solution.

I have sample data table.



Add index column in Edit Query-> Close & Apply. You will get the following table.



Create a calculated column using the formula.

Last = LOOKUPVALUE(Table9[value],Table9[Index.1],Table9[Index.1]-1)

Finally, create a measure. For unique date, sum(Table9[value]) equals itself. Create a table visual used to display the result.

Percentage1 = (SUM(Table9[value])-SUM(Table9[Last]))/SUM(Table9[Last])

If you have other issues, please let me know.

Thank you Angelia,

I think this is the solution. I'll have to adapt to my model in order to have the right sequential index.

Best regards
