I have done this 2 ways: a. use %let = variablename (such as year, month day) and then referencing them as macro variables or b. use a data step to set the variables and then referencing them as macro variables Using method a: %let rundate = %SYSFUNC(today(),yymmddn8.); %let runhour = %SYSFUNC(HOUR(%SYSFUNC(time(), MINUTE.)), Z2.); %let runmin = %SYSFUNC(MINUTE(%SYSFUNC(TIME(), MINUTE.)), Z2.); then set variable to use the above values: %let exportfile="REPORT_as_of_&rundate._&runhour.&runmin..xml"; Note the extra period after each macro variable when it is referenced using &. OR Using method b: Create a table that gets the "rundate": PROC SQL;    CREATE TABLE WORK.GET_REPORT_RUNDATE AS    SELECT DISTINCT /* REPORT_RUNDATE */                      (DATETIME()) FORMAT=NLDATM30. AS REPORT_RUNDATE       FROM WORK.GET_ALL_TESTS t1; QUIT; Then use a data step to break apart the datetime: data temp;   set work.get_report_rundate;   rundate = datepart(report_rundate);   year = year(rundate);   month = month(rundate);   runtime = timepart(report_rundate);   hour = hour(runtime);   minute = minute(runtime);   format month z2.;   format hour z2.;   format minute z2.;   charmonth = put(month, z2.);   charhour = put(hour, z2.);   charmin = put(minute, z2.);   reportrundate = year||charmonth||'_'||charhour||charmin; run; Then, reference those macro variables : %let exportfile="REPORT_as_of_&rundate._&runhour.&runmin..xml"; ...
