To generate partial snapshot
- Go to publisher
- Add extra article by right clicking on publication
use <replicateddbname>
go
exec sp_changepublication

, @property=N'allow_anonymous'
, @value='false';
go
exec sp_changepublication
@publication=N'TestDBTP'
, @property=N'immediate_sync'
, @value='false';
go
- Now run snapshot agent
- Check that snapshot is generated only for newly added article.
