I have simple table in Power BI, where I have created a measure (% Compliance error percentage) as Total error count / open opportunities:
% Compliance error percentage =
DIVIDE(SUM('Data compliance'[Total error count]),
sum('Data compliance'[Open opportunities]),
The data is logged every two weeks (week 1, 3, 5 and so forth as per the table below).
This simple calculation works fine. However, instead of showing the 'error percentage' I would like to show the 'valid percentage' by subtracting the error percentage from 1. E.g., 'valid percentage' for week 1 will be 93,75%.
The issue is that if I make a simple measure like this:
% Compliance valid percentage =
1 - [% Compliance error percentage]
I will end up with values for all dates, also the ones where we haven't logged any data, since 1-0 will return a value.
My question is now - is there a way I can limit the measure to only make the calculation for the rows that have data?
I have tried with varies IF statements but I haven't found a solution,.
