000745: Generation numbers are out of order.

Description

This error happens when you are attempting to import new replica data changes before an earlier set of changes has been imported. This can happen if an earlier data change message has been lost or if delta files are imported out of order.

Solution

One way to solve this issue is to resend all unacknowledged data changes from the replica, which was the source of the data changes, and import these into the relative.
