Remarks
sp_repldropcolumn is used for all types of replication.
When using sp_repldropcolumn, if a schema change is made to an article that belongs to a publication that uses a DTS package, the schema change is not propagated to the Subscriber, and the custom procedures for INSERT/UPDATE/DELETE are not regenerated on the Subscribers. The user will need to regenerate the DTS package manually, and make the corresponding schema change at the Subscribers. If the schema update is not applied, the Distribution Agent may fail to apply subsequent modifications. Before making a schema change, make sure there are no pending transactions to be delivered. For more information, see How Transforming Published Data Works.
Important A backup of the publication database should be performed after sp_repldropcolumn has been executed. Failure to do so can cause a merge failure after a restore of the publication database.
