Tables, stored procedures, and sequences must be marked for replication and have replication enabled for the object (table, stored procedure, or sequence). LOB columns must have replication enabled, and the table that contains the LOB column must be marked for replication and have replication enabled for that table.
There are five types of objects that can be marked for replication in a primary database:
Tables
Stored procedures
Large-object (LOB) columns
Database Definition Language (DDL)
Sequences
