sql server replication: Dear friends

I have got the following unresolved conflict for the
replication. We are using the merge replication.

Datetime,UserAction,Database,Publication,Table,Origin_Data
Source,RowGuidValue,conflict_type,reason_text,SQL
20/02/2004 15:45:58,"Conflict
Loser","MainSQL","BPOMainSQL","[dbo].
[SAL2004]","cool.BPOSQL","{E69DDB18-4BAF-45E4-8006-
E90BF8914AA9}","5","The row was inserted at 'COOL.BPOSQL'
but could not be inserted at 'MATRIX.MainSQL'. Violation
of PRIMARY KEY constraint 'PK__SAL1__03FB8544'. Cannot
insert duplicate key in object 'SAL2004'.","",

Please suggest what action i should take to solve the
problem.

Best regards

you could partition the data to make sure each subscriber and the publisher receive different primary key values. This could be done using identity ranges for a surrogate PK or by having a multi-column PK, one column of which has a site identifier
