Hi,

 

I have the following code in the optmodel:

 

for {i in rxid} do;
if calculation[i] = 1 and dollars[i] =1 > current_copay[i] +5 then do;
fix copay1_lhs[i]= n_ingred_cost[i] + n_disp_fee_final[i] ;
fix copay1_rhs[i]=(current_copay[i] +5) - bill_tax[i];
end;
end;
con c28{i in rxid}:copay1_lhs[i] <= copay1_rhs[i];

 

when i expand it, i see the results below

 

Constraint c28[674523592]: copay1_lhs[674523592] - copay1_rhs[674523592] <= 0
Constraint c28[674563238]: copay1_lhs[674563238] - copay1_rhs[674563238] <= 0
Constraint c28[674563792]: copay1_lhs[674563792] - copay1_rhs[674563792] <= 0

 

is it right to pass the variable in the constraint function; please help

 

thanks in advance

I think you want the following:

   con c28{i in rxid: calculation[i] = 1 and dollars[i] = 1 > current_copay[i] + 5}:
      n_ingred_cost[i] + n_disp_fee_final[i] <= (current_copay[i] + 5) - bill_tax[i];

ya exactly, i tried your code ,but could not see anything in the expand results. will the constraints be applied there?

If the logical conditions after the colon operator are never satisfied, then the index set is empty and EXPAND will not display anything.  This part of the condition is suspicious:

dollars[i] = 1 > current_copay[i] + 5

What is the intent here?
