Here is my set up:
Proc ESM data = cwork.forecastworked out = forecastedworked Lead = 1;
ID Mon_1_1_YY interval = month accumulate = average;
I know I can change Lead = 1 to say Lead = 4 or 5 or 6 to get months more than 1 ...
My id variable is a month variable so i'm good there.
I am storing about 6 months of data for history....what happens is that it does forecast all the months I ask for but gives the same value for each month of that of the first forecasted value...is it because Im not giving it enough historiy?
Hopefully im clear enough on my concern....thanks,.

There are at least 2 things you might want to need to consider:
set sashelp.air(where=(date ge "01JUL60"d));
PROC ESM ESM data=have out=want Lead=3 plot=forecasts;
air / model=DAMPTREND;
Hope this helps,
