forecasting with categorical and quantitative variables

Hi,

I have a time series with the following independent variables:

time, vendor, product, miles driven

time is the time variable

vendor and product are categorical variables

miles driven is a quantitative variable

Will it be statistically correct if I did the following:

proc autoreg data=MyData;
 class vendor product;
model sales = vendor product miles_driven;
 run;

Its just that the few times when I did time series I only had time as an independent variable, but here there are categorical and quantitative variables as well so I just want to make sure that using the proc autoreg will yield meaningful results.

Thank you
