How to: Replicate Schema Changes (SQL Server Management Studio)
By default, the following schema changes made at a Publisher running SQL Server are replicated to all SQL Server Subscribers:
If you do not want to replicate schema changes for a publication, disable the replication of schema changes in the Publication Properties - <Publication> dialog box. For more information about accessing this dialog box, see How to: View and Modify Publication and Article Properties (SQL Server Management Studio).
The ALTER TABLE … DROP COLUMN command is always replicated to all Subscribers whose subscription contains the columns being dropped, even if you disable the replication of schema changes.
To disable replication of schema changes
On the Subscription Options page of the Publication Properties - <Publication> dialog box, set the value of the Replicate schema changes property to False.
To propagate only specific schema changes, set the property to True before a schema change, and then set it to False after the change is made. Conversely, to propagate most schema changes, but not a given change, set the property to False before the schema change, and then set it to True after the change is made.
