[Scip] about dual solution

Dear all,



I used SCIP to develop a B&P method, in which soplex is used as the LP solver. 

For some "<=" constraint, soplex produced positive dual solution. This value should be non-positive.  I used CPLEX to solve the corresponding LP.  The corresponding dual solution is zero. 

Any reason for this situation?  

Thanks.
