Just to clarify.
1) I fix the variable before solving and when pricing a new column, I try to change the bounds. I guess it will not work, correct?
2) My other option is to delete variables before solve and add them as I price. But delete doesn't work too or I am not doing it right?
Thanks,
Vivek.

Subject: Changing the bounds of a FIXED variable
Hello,
1) Is there a way to change the bounds of a fixed variable? I fix it using SCIPfixVar() but SCIPchgVarLb() and SCIPchgVarUb() does not allow me to change the bounds.
2) How to delete a variable from the problem object. If I do SCIPdelVar(), the variable is marked for deletion but it's not deleted from the problem object.
Regards,
Vivek
