Character date to numeric date & ACF plot

Hi I'm plotting the ACF of CAD with the following data example:

However, the log gave the following error:

So I guess the problem is my date is not numeric? If so, can someone provide some hint with this problem? Thank you.

Here is the code I wrote for ACF plot:

proc autoreg DATA=Combined
plots(unpackpanel only) = ACFPlot;
model CAD = Date;
run;

Have you tried adding the class statement prior to the model statement? Could be that SAS wants to look at your data categorically.

CLASS Date;

Also, what is the informat and format of your data?

Thank you for replying, I double checked the format part and fixed it by correcting a mistake. Thank you.
