Constraint with more than 2 elements in tupple

Hi,

I am running below mentioned code...

proc optmodel;

ods output SolutionSummary=exss;

set <string> itm_list;
set <string,string,string,string> itm_hrchy;
set <string,string,string,string,string,string,number,number> dsp_prc_choice;

number beg_stk{itm_list};
number curr_dsp{itm_hrchy};
number cogs{dsp_prc_choice};
number org_prc{dsp_prc_choice};
number sugg_prc{dsp_prc_choice};
number sugg_dsp{dsp_prc_choice};
number qty{dsp_prc_choice};

read data table1
into itm_list=[itm_cd] a=...;

read data table2
into itm_hrchy=[grp_cd dpt_cd cls_cd sbcls_cd] v=...;

read data table3
into dsp_prc_choice=[grp_cd dpt_cd cls_cd sbcls_cd curr_ssn_cd itm_cd display_str sug_rtl_prc] qty=&qty_value. k=... l=... n=... m=...;

var x {<grp,dpt,cls,sbcls,ssn,itm,dsp,prc> in dsp_prc_choice} binary;

max obj = ...

con1 ...;

con2 ...;

con sbcls_dsp{grp,dpt,cls,sbcls in itm_hrchy}: sum{<(grp,dpt,cls,sbcls),ssn,itm,dsp,prc> in dsp_prc_choice} m[grp,dpt,cls,sbcls,ssn,itm,dsp,prc]*x[grp,dpt,cls,sbcls,ssn,itm,dsp,prc] = v[grp,dpt,cls,sbcls];

con3 ...;

solve with milp / relobjgap=0.1;

create data solution from [grp_cd dpt_cd cls_cd sbcls_cd curr_ssn_cd itm_cd sugg_dsp_str sugg_rtl_prc] = {<grp,dpt,cls,sbcls,ssn,itm,dsp,prc> in dsp_prc_choice: x[grp,dpt,cls,sbcls,ssn,itm,dsp,prc] = 1};

run;

I am getting error in the "sbcls_dsp" constraint declaration. Following error is coming -

You are missing some angle brackets and parentheses. Try this:

   con sbcls_dsp{<grp,dpt,cls,sbcls> in itm_hrchy}:
      sum{<(grp),(dpt),(cls),(sbcls),ssn,itm,dsp,prc> in dsp_prc_choice}
