Accumulative measure over weekno with historical data

[AneZ]

I have made a measure that accumulates over week_number:

acc actual 2018 = calculate(sum('actuals 2017[2018 Actuals]);
Filter(Allselcted(Actuals 2017); Actuals 2017[weekno] <= max(Actuals 2017[weekno])))

but when i plot the measure with weekno i get a plateau that I dont want, since it is still some weeks without data for 2018. I want the graph to stop at week 49, so that i instead of have a plateau can ha a prediction for what's left of the year.

I tried to make a measure that returns blank when the weekno we are currently in are higher than the weekno i am trying to accumulate. 

chec = IF( CALCULATE ( MAX ( Actuals 2017[weekno]); ALL(Actuals 2017[weekno])) < WEEKNUM(TODAY()) ; [acc actual 2018] ; BLANK())

But when i do this the measure refuses to be plotted with weekno. I can't see anything..

Can someone help?? 🙂

Hi @AneZ,

I'd like some sample data to help us clear your table structure and test to coding formula.
