You can include as many as 1024 columns in a replication definition. As long as the total number of columns does not exceed 1024, Replication Server does not limit the number of primary key or searchable columns.
Replication Server uses primary key columns to build where clauses of SQL statements for the data server. Consider data server limitations when determining the actual number of columns available for primary keys in replication definitions.
Similarly, although Replication Server imposes no limits on the n umber of searchable columns in a replication definition, the number of columns in the where clause of a subscription or article may also be constrained by data server limitations.
