MSrepl_tran_version - needed or not?

Hi
Can someone please tell me, when i setup a publication for
transaction replication (push only), sometimes it says:
"SQL Server requires that all articles in a publication
allowing updatable subscriptions contain a
uniqueidentifier column named 'MSrepl_tran_version' used
for tracking changes to the replicated data. SQL Server
will add such a column to published tables that do not
have one"
But other times it does not ask to do this, and i have
successfully had a replication running without the
requirements is says. Do i need it or not?
Hi
If you want the changes to be replicated from the subscriber to publisher,
using immediate updating or queed updating, it becomes a requirement that
uniqueidentifier column is needed. If you dont want the reverse update, then
you may not need that column. Hope it helps
