We have some tables published from one SQL server and another server subscribed to it. However we just realised on two tables data was added at the subscriber end that doesn't exist at the publisher. I can easily enough insert those rows at the published end but I'm struggling to find information that will confirm what will happen when it tries to replicate, so would appreciate some guidance.
Would I need to reinitialise the subscription or handle the conflicts another way? Or what would be the simplest way to get that data back into the publisher. This is a one-off - in future all updates will be at the publisher.
Thank you
