    Hi, 

    I am getting conflicts and relaxation in two constraints of my opl project. i have tried to fix them but i am unable to locate them. i am new to the cplex and are not much familiar with, how to fix the conflicts among different constraints. Kindly help me fix/locate them. I am looking forward to hearing from the team of IBM and my seniors. attached are the files of my conflicts and relaxation window and also i have attached my .data files. thank you

    The output says that certain instances of Const1 and Const3 are in conflict. The indices for the respective constraints are hard to interpret. You may want to go to the settings file and crank up the long name threshold parameter so that long names in indces are not replaced by numbers. With that you should get more readable references to the constraints in the conflict display.
