Fields are the elements within an article. A field represents the smallest database object that can be identified for replication. In tables, fields identify columns. In stored procedures, fields identify input parameters.
When you create a primary article, you can either publish all fields, or you can specify a subset of the fields for publication in that article. Likewise, when you create a replicate article, you can either subscribe to all published fields in the primary article, or you can specify a subset of the published fields to be subscribed to.
By specifying fields in both primary and replicate articles, you have two levels of selection to determine the data replicated.
