I tried MCKP (bicriteria knapsack problems) application and it works. I also want to run other bicriteria problems which I don't know how to do that.

Apparently it does.
It has been a while since I actually used Symphony.
Appently one has to add the second objective
and invoke mulitCriteriaBranchAndBound.
I'm unclear n how one collects the solutions.
Presumably this is all the same for MCKP.
What particular problem are you having?
