What is the best way to build a statistic model to predict values in SAS Visual Statistics?

Hello,

I need to predict the values for Y (dependent variable). Y is numeric but in our case it is not a continuous value but rather a discrete and categorical value with order. The X (independent variables) are categorical values as well. 

I need to predict Y over time, e.g. over the next six months. What is the best way to build this model in SAS Visual Statistics? I was trying to build a time series line chart with the forecast. However, the Y values are aggregated because there are multiple values on a given day. I don't need the aggregated (either sum or average) values. 

Thanks,

If you aren't aggregating how are you differentiating between the different values on the same day?

I guess that's my question...since aggregating the values probably doesn't make any practical sense in our case.
Also, given the data types, is it appropriate to use the series line chart to do the forecasting?
