MORE INFORMATION

This problem occurs under the following conditions:
  • One main publisher/distributor server (ServerA) has a publication P1.
  • One republisher/distributor server (ServerB), which has a pull merge subscription to P1 on ServerA, republishes P1.
  • One subscriber (ServerC) has a pull merge subscription to the publication P1 on the republisher server (ServerB).
  • On the main publisher server (ServerA), add publication P2.
  • Publications P1 and P2 do not have overlapping articles.
  • On the republisher server (ServerB), add a pull merge subscription to P2 on the main publisher server (ServerA), and then republish P2.
When the initial snapshot of publication P2 is applied from the republisher server (ServerB) to its subscriber (ServerC), the pull merge replication process fails with the errors shown in the "Symptoms" section.
