You can create a mapping from the Replication Process Mapping Editor (RPME) dialog box using any of the following way:
A mapping corresponds to a publication — subscription couple. You can create several different mappings for the same source object. Each mapping is added to the mapping pane that allows you to parameter the mapping.
As soon as you create a mapping (in terms of publication — subscription) a publication for the data connection you use is created and displayed in the properties pane. Besides, an article or article column corresponding to the object to replicate is displayed in the properties pane. If you delete the replicated object you do not delete the associated publication. But if you delete a publication, all the replicated objects that use the publication are deleted.
