%LET JOBNAME=acardact_;

data _NULL_;

date1=intnx('MONTH',today(),-1,'SAMEDAY');

CALL SYMPUT("LOAD", TRIM(LEFT(PUT(DATE1, YYMMN6.))));

LOAD_T= "&JOBNAME"||"&LOAD";

CALL SYMPUT ("LOAD_DATE", LOAD_T);

%PUT &LOAD_DATE;

run;

Expecting value----- acardact_201401

You can't put a macro variable that doesn't even exist... + (&x).

A is a data step variable in your example, not a macro variable.

Data never sleeps

Since macro variables are evaluated at compile time, date1 haven't been set at that time.

Just use data step variables, and then do call symput at the end.

Or just use macro code, not necessary to use a data step for this kind of logic.

Move the RUN; statement to before the %PUT statement.  You have to force the DATA step to complete in order to create your macro variable.
