i configured the SQL server as transactional replication server A as publication and server B as subscription. In the server B i modified the replicated table and add columns on it. i reconfigured the replication both from the publication and subscription then i was shock that the additional columns i made before was now gone in the server B i am afraid in the future scenario when re configuring the replication from both server will delete the columns along with the added data on it.
did i do something wrong? i run the query sp_removedbreplication from both server. then both set up the replication up again.
