I need to replicate some data from two tables in one database to another databases. I used snapshot replication. The issue is that I would like to replicate only some selected columns and the others should stay with untouched data. I don't want to loose their data. The source of those columns is other system. So I need to replicate only data from my columns. Do anybody know how to achieve this?

Should the 'untouched data' columns stay untouched at the publisher or at the subscriber?

At the source, vertically filtering the articles works with all replication models, see Filtering Published Data and How to: Define and Modify a Column Filter.

At the subscriber both merge and transactional replication allow this, if properly initialized, but snapshot replication definitely does not.
