help with a formula to filter the sum of a calculation
I am trying to perform what is seemingly an easy calculation but I cannot get there in DAX.
I am reading several forecats files, to which I give a version: "n" for this month, "n-1" for last month, etc.
I also have an actual spending table, with spending per month up to the latest month of available data (so no versioning).
What I need to do it to be able to sum up the actuals but only up to the date of the version selected (or version used as a legend in a chart is what I would like to achieve, to show the different curves of forecast + actual per month by file version).
I have a table with file versions that I am reading, that I have now included in my date table (which I hope is the correct way of doing thigs):
The Actuals table just has 4 columns: Project Number, Date, Spending and Year
then I have tried to created a measure for summing the actuals, but it is not working 😞
