list reports with calculated percentage in Power BI using dax

Question

I have a Power BI report with multiple lines (it's a P and L report) displayed in a list visualisation.

It's populated from a view in SQL

One of the lines is 'Total Revenue'

I need every line to display its proportion of Total Revenue as a percentage:

i.e.

LINE           MTH     %
------------------------
Line1            5    10 
Total Revenue   50   100
Line2           20    40
Line3            4     8
Line4           12    24

Note that MTH does not add up to total revenue so I can't just take the total, I need to take the line called Total Revenue as the denominator

Answer 1

Create a Measure called Total Revenue:

Total Revenue = 
SUMX(
    CALCULATETABLE(
        'vw_PandL',
        'vw_PandL'[Line] = "Total Revenue"
    ),
    [MTH]
)

Create another Measure called %:

% = VALUES(vw_PandL[MTH]) / [Total Revenue]

And it will work with filters applied.
