Hi,I am trying to create Merge replication with following steps and error below1. Create DB - Publication and Subscriber on same instance2. Create table with INT Identity primary key and few other nullable character columns - It has no FK.3. Added column ROWGUIDCOL manually in tables at both side4. updated ROWGUIDCOL with same value on both side5. Added publisher6. When i add subscriber, I am getting following error. I have tested this scenario with different table structure but of no use and even output file gives similar details[b]Question: I just want to understand, on which column it is trying to create unique index?[/b]If ROWGUIDCOL has same value on both side and inface same table structure and data on both side and if merge replication checks for rowguid col for sync then what is the purpose of this error.Thanks for your help.[quote]Error messages:Message: The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.myTable' and the index name 'MSmerge_index_856103282'.
