Replication supports publishing articles in multiple publications (including republishing data) with the following restrictions:

•  If an article is published in a transactional publication and a merge publication, ensure that the @published_in_tran_pub property is set to TRUE for the merge article.
•  An article cannot be published in both a merge publication and a transactional publication with queued updating subscriptions.
•  Articles included in transactional publications that support updating subscriptions cannot be republished.
•  Transactional replication and unfiltered merge replication support publishing a table in multiple publications and then subscribing within a single table in the subscription database (commonly referred to as a roll up scenario). Roll up is often used for aggregating subsets of data from multiple locations in one table at a central Subscribe
