[SCIP] set cutoffbound

Dear all,
I'm working on a branch-and-price algorithm, and I want to apply a
primal heuristic each time a feasible (integer) solution. Basically, I
build a /schedule/ based on this solution, and I apply a local-search
based approach to improve this schedule, and thus to get a better
feasible solution. My problem is that I cannot create a SCIP solution
since it may require columns/variables which are not generated for the
problem yet. Actually, I do not need to create such a solution, it would
be enough if I could set a cutoff bound for the problem (that is, to set
a global upper bound for the objective, and thus nodes with higher
lowerbound could be pruned. (Note that I did not implement primal
heuristic callback due to the reasons mentioned above, but I apply this
procedure in an event handler).
I could not find such a parameter in the list of all parameters, and I
could not find solution for this problem in the list server archives.
Can you help me?
Best regards,
Marko
