Yes, you need to keep a mapping from the current from the current active 
rows to your original rows if you want to know which row is which. You 
would need to do the same thing for the columns, if you are going to 
actively manage those.

This is not specific to Osi. The same would be true if you used CPLEX 
callable directly, or almost any other callable library.
