There are several requirements if you want to create a replication definition for a table that contains text, unitext, or image columns datatypes.
Include each text, unitext, or image column that you want to replicate in the column list, and
Include each column in the optional clauses replicate_if_changed or always_replicate.
In each clause, enclose the names of the text and image columns in parentheses. For multiple columns, separate each column from the next with a comma.
Ensure that each text, unitext, or image column has a corresponding status in Adaptive Server.
