The data table creation date is sometimes necessary, say in the footnote of your stored process. Included below is a sample to retrieve this date from the file system.

/*Open the dataset*/
%let dsid=%sysfunc(open(sashelp.shoes));
data _null_;
/*grab the CRDTE function*/

ddate=%sysfunc(attrn(&dsid;,CRDTE ));
/*Format in DDMONYY*/

call symput('ddate', put(ddate, dtdate9.));
run;
/*Close the dataset*/

%let rc=%sysfunc(close(&dsid;));

//*Sample use of the create dataset macro*/

footnote "Data Refreshed On &ddate;";
proc gchart data=sashelp.shoes;
vbar sales;
run;quit;
