Can anyone suggest me the solution to this problem?

I have a decision expression as :

dexpr float R = (sum(s in Facility,c in Customers,i in ProductsdRawMat,t in Periods) -shortCost[c][i]*Supply[s][c][i][t]);

minimize R;

subject to 

{

R<= e[i]

}

Where "e" is a value which going to change from 1 to 1000,

And, I need to run my model 1000 times to satisfy my this constraint because I need to change "e" value every time, So, I want to put this "e" value in a loop which runs this model 1000 times with change the "e" value.

I m very new to this OPL. Please help me
