Hi DBA┬┤s, I need help with issue of transactional replication,
this issues is , when i want to create a transactional replication at time of select the articles to publicate, in the botton of the wizard appear a message that say, This table cannot be published because it does not have a primary key column. Primary key columns are required for all tables in transactional publications.

Someone to help fix this issue.

Thank for you help.

In transactional replication, it need a primary key for each table to replicate. It is a way to uniquely identify each row of a replicated table, so that, when changes to a row are replicated to the subscribers, there's no doubt as to which row the change must be applied.

Snapshot replication, since it just copies tables as they appeared at a specific point, does not have this requirement.
