257 (E)- Invalid transaction number %1 passed from replication client (current TA: %2)
Synchronizing a replication client with the replication master (server) creates an error. Probably to many transactions had been processed on the master, i.e. the difference between last server transaction and last client transaction is greater than the maximum number of transactions assigned to the server.
Other reasons for this error are different versions for the replication database or different creation dates. Use DBSystemInfo() and DBSysInfo() for checking versions for replication server and client databases.
When the error persists after restarting the application, check, whether the database backup located on the replication server is outdated.
