Hi to all:
I have a new publication wich have a subscriber with loopback_detection set to True, because in the subscriber the is another publication wich have articles that are also in the first publication. in this way I avoid re transmiting transactions and duplicate key errors.
But because I'm testing it, sometimes I have to drop the subscription to one article, drop the article,make some changes and then and the article and refresh the subscription (using sp_refreshsubscriptions).
