Are you using the GUI time series system to do all 140 series?

If not, what procs are you using?

Why do these all have to have the same end date?

How far off from the last end date are the other time series?

How much damage will it do to your work if some of the time
series have forecast values at the end instead of real values, so
that their values have much larger variances than the other
series and/or data points?

And what would happen if, instead, you chose the EARLIEST
ending date as the last date for all the time series?

HTH,
David
