Dear -alls,
In my Database there are few tables which have'nt any Key column/s, and when i go for replication then found its Mandatory to have a key column in a table to which I want to replicate - (DB2 UDB 7.2 replication scenario)- so if anyone here have any solution ? - i mean, i suppose to add key column in table or there is another way to do replication without it.
any help or guidance in this regard really appreciate.
Thank You.

No, you really need a primary key or a unique index on the table you want to replicate. If you update a row in the source database DB2 needs to know which row should be updated in the target database which isn't possible without a unique key.

Kind regards, Gert
