The table %1!s! contains the column msrepl_tran_version, which is used by replication. The column is set to NULL, but it must be set to NOT NULL. Replication failed to alter this column, so you must drop the column and then add the table as an article again using sp_addarticle. Replication will then add the column to the table.
