Calculate Total Expenses Excluding Current Month

Hi All,

I want to show a bar chart comparing month by month 2 different measures:

a) Total actual expenses (from the origin to the last month extracted -but excluding the current month-)

b) Total expenses budgeted (from the origin to the end of the project; in this case we don't have to exclude any date)

My question would be what measure can I use for the Total Actual Expenses (a), excluding the current month inside the formula?

I think it has to be inside the formula. The problem is that I can't use a slicer as a filter for dates for the specific visual object, as I do want to show all dates for the comparative measure "Total expenses budgeted (b).

So I think that the only solution would be to create a measure with CALCULATE filtering dates in somewhow... E.g.:

CALCULATE ([Total actual expenses];ALLEXCEPT('DATES';¿(current month)?))

Another idea? I would be very grateful if someone could solve this question.

Thanks

Regards
