We're just adopting Power BI, and I need to build a report with a matrix in it:
Rows are year
Columns are product and size
one view to show volume sold (which is easy), one to show % of size sold for each product, so each product's %s add up to 100 for each year (which is doing my head in). eg. for Product A, 30% Small, 50% Medium, 20% Large. Everything's in one table with
customer number, transaction date, product, size
It should be doable in DAX but my knowledge of that is currently limited, any experts to give me the correct expression?
What's the data in? Sql? Do a view of the data first and work the sql server
Yep sql server is the source, I could just fix it in the query but thought DAX would be up to the job.
Sorted!
% Sales = count(customer number)/calculate(count(customer number), ALLSELECTED(size))
