Merge replication

Hi all,

  I'm using Microsoft SQL Server Business Intelligence (64-bit) for the Merge Replication for both Publisher & Subscriber.

After configuring Bi-directional Merge replication i'm getting the below error Message for some tables As Conflicted Rows.

A row update at 'Server A' could not be propagated to 'Server B' . This failure can be caused by a constraint violation. Explicit value must be specified for identity column in table 'Table A' either when IDENTITY_INSERT is set to ON or when a replication user is inserting into a NOT FOR REPLICATION identity column.

Note ; There is a trigger on  'Table A'  both side at Publisher & subscriber. which is dependent on other tables too.

 I'm new to Merge Replication Can u plz help for this error.

Thanks in advance.
