Dear,

I am running a macro that has this    "proc sort data=_final0 out=&OUTPUT_DATASET.(label=&dslbl); by &sortby; run;"

The macro variables are resolving &OUTPUT_DATASET and &dslbl and &sortby   all are resolving. Below is the resolving code.  But I am getting errors because the semicolon is missing in resolved code after Label statement and before By statement eventhough there is semicolon in macro Label statement and before By statement. Please suggest. Thank you.  I am also copied the log file where it showing error (22). 

proc sort data=_final0 out=lptda.addili(label=DILI Reporting Analysis Dataset (SI)) by USUBJID
PARAMCD AEPOCH ADT ;
MPRINT(ADD0ATTRIBUTE): run;

Your label ends with a ")". Try using double quotes around your label macro:

(label="&dslbl");

You also want to be very cautious about using *statement; style comments in macros.

Either use the %*statement ; or /* statement; */

Under some syntax combinations the statement style comment may be submitted as code to be treated as though it should be executed.

Let's not forget the elephant in the room that leads to the problem.

PROC SORT works just fine. There's no good reason to turn it into a macro. All that accomplishes is adding complexity, clouding the debugging process, and eliminating the possibility of applying other options (such as NODUPKEY) .
