There are several guidelines to follow when you create a table replication definition for text, unitext, image, or rawobject columns.
Include each text, unitext, image, or rawobject column that you want to replicate in the column list.
Specify the datatype for each text, unitext, image, or rawobject column.
Specify whether a null is allowed for the column in destination tables. This setting must be consistent with the way the source and destination tables are defined.
Include each column in the optional clauses replicate_if_changed or always_replicate.
