Hi,
I have calculated "TTM avg." below with Member Formula: @AVGRANGE(SKIPMISSING,"MTD", @CURRMBRRANGE("Period", LEV, 0,-11,0));
How do I modify the formula so that the calc extends across Years rather than restarting in Jul?
Or to put it another way, how do I calculate the green row in the 2nd screenshot rather than the orange row?


TIA
