Column Invalid for Replication Timestamp

When attempting to set CHECK CONFLICTS for an element in a CREATE REPLICATION statement, you may encounter an error similar to the following.

8004: Column REPL.TABS.TS cannot be used for replication timestamp checking if 
in an index or added by ALTER TABLE; and must be binary(8) with NULL values allowed.

In this situation, check:

• That the timestamp column in the specified table is a nullable column of type BINARY(8). In the above example, the TS column in the REPL.TAB table should have a type of BINARY(8).

• The timestamp column is defined in the original CREATE TABLE statement, rather than added later using ALTER TABLE.
