Save Residuals from ARIMA PROC

I need help in the following situation:
I have estimated the p and qs of a ARMA(p,q) model with the SAS PROC (ARIMA) in the following form:

PROC ARIMA data = fdx;
title 'ARMA_R';
identify var = R nlag=12;
estimate p=2 q=2;
RUN;

R(t)=a + bR(t-1)+bR(t-2)+u(t)-o(1)u(t-1)-o(2)u(t-2)

The model fits the data very well.
Now, I would like to use the errors u (for every t) in a other regression model. How can I save these numbers in a new table?

Thanks!
