Forgetting the features and rules of SQL Remote for the moment, what exactly do you want to happen? (from your databases' point of view).
What exactly do you know about the current situation? (e.g., do you know what the affected rows contain in all the columns, or do you just know the primary keys, or something else?)
Is the situation stable for the affected rows? Or are they being repeatedly updated and replicated?
What version of SQL Anywhere are you running on the consolidated and remotes?
(no, don't mess with offsets, that never works for mortals)
