Distinguish changes by replication and changes by user

Hello,
Merge Replication, SQL Server 2005
I have got a table with an update trigger that is supposed to fire when a
user updates a field.
When replicating this database, the trigger fires when a user updates a
field *and* when the update is performed by the replication process.
How can I avoid the latter? Is there a TSQL-function to distinguish the two?
Thanks for your effort, Wolfgang
Another way is to hack into the sessionproperty
ie if ('replication_agent') <> 1 then its a user action.
Looking for a SQL Server replication book?
