Hey Amir,<br>
<br>
we need some more information to help you with your problem. Could
you send us your model or code, please?<br>
<br>
In general, SCIP does not provide dual information. This is directly
passed through from the LP solver and only available if you disabled
presolving.<br>
Are you solving a MIP or an LP?<br>
<br>
cheers<br>
