Thank you for your assistance.

Do you really need a macro to read in that datasets? Why not to use "data sets list", see example:

libname werkwm (work);
data
  werkwm.martaccount202210
  werkwm.martaccount202211
  werkwm.martaccount202212
  werkwm.martaccount202301
  werkwm.martaccount202302
  werkwm.martaccount202303
  werkwm.martaccount202304
  werkwm.martaccount202305
  werkwm.martaccount202306
  werkwm.martaccount202307
  werkwm.martaccount202308
  werkwm.martaccount
  ;
  set  sashelp.class;
run;

options noDSNFERR; /* to use data sets list (e.g., SET A1-A111;)
                      and don't get error if any from the list is missing */
data ALL;
  set 
    werkwm.martaccount202210-werkwm.martaccount202308 werkwm.martaccount
  ;
run;
options DSNFERR;

[EDIT:]

The SET statement with a "data sets list" of the form A1-A5 usually expects that all datasets A1, A2, A3, A4, and A5 exist. In you case the range 

werkwm.martaccount202210-werkwm.martaccount202308

for sure will have some "gaps" (we don expect to have 202214,202215,etc.) that's why the noDSNFERR option solves the problem, basicall it says to SAS: "if a data set from the range does not exist ignore that and go to the next one"

I can do that, but the problem is , i want to automate this piece of work, so wont it be better to just have the macro running to read the data whole time ?

Then how about something like this:

libname werkwm (work);
data
  werkwm.martaccount202210
  werkwm.martaccount202211
  werkwm.martaccount202212
  werkwm.martaccount202301
  werkwm.martaccount202302
  werkwm.martaccount202303
  werkwm.martaccount202304
  werkwm.martaccount202305
  werkwm.martaccount202306
  werkwm.martaccount202307
  werkwm.martaccount202308
  werkwm.martaccount
  ;
  set  sashelp.class;
run;

%macro ListFiles(lib,ds,date);
%local start end;
%let end  = %sysfunc(intnx(Month,"&date."d,-1 ,S),yymmn6.);
%let start= %sysfunc(intnx(Month,"&date."d,-12,S),yymmn6.);
&lib..&ds.&start. - &lib..&ds.&end. &lib..&ds.
%mend;

options noDSNFERR; /* to use data sets list (e.g., SET A1-A111;)
                      and don't get error if any from the list is missing */
data ALL;
  set 
    %ListFiles(werkwm,martaccount,1sep2023);
  ;
run;
options DSNFERR;

The code still uses "noDSNFERR" option.

The "date" parameter should be set for "month with no date in dataset name", in this case September 2023.

Add "options Mprint;" to see how it is resolved under the hood.

It's a bit hard to know your exact requirement, but if you need a list of datasets for a 12 month period, here's some (untested) code you can start with. If you want to fully automate you can use &sysdate in the beginning to specify your start period. Since I didn't know how you'll select the 12 month period I didn't include that in my logic.

%let start=%sysfunc(intnx(month,%sysfunc(inputn(&end.01,yymmdd8.)),-12), yymmddn8.);
%put &start;

proc sql;
	select catx('.',libname,memname) into: martaccounts separated by ' '
		from dictionary.tables
		where memname between "MARTACCOUNT&start" and "MARTACCOUNT&end"
			and libname = 'WERKWM';
	select catx('.',libname,memname) into: martvtraxapplications separated by ' '
		from dictionary.tables
		where memname between "MARTVTRAXAPPLICATIONS&start" and "MARTVTRAXAPPLICATIONS&end"
			and libname = 'WERKWM';
	select catx('.',libname,memname) into: martvtraxdealers separated by ' '
		from dictionary.tables
		where memname between "MARTVTRAXDEALERS&start" and "MARTVTRAXDEALERS&end"
			and libname = 'WERKWM';
quit;
