Remarks

Transactional replication requires a primary key to identify rows. For SQL Server installations, primary keys are implemented in PRIMARY KEY and UNIQUE key constraints.

If True, the table contains a PRIMARY KEY constraint and can be published as an article in a transactional publication.

If False, the table does not contain support for transactional replication and cannot be published as a transactional article.
