Hello Peter,

I'm glad it's possible, but I can't see how from the documentation.

Say if I have a table called 'apples' and a table called 'pears'.

What would the rule look like that would remap all updates on apples so that
they were applied to pears instead?

Thanks,
Andy

You can write a couple of rules for that.
