Result set
sp_repltrans returns information about the publication database from which it's executed, allowing you to view transactions currently not distributed (those transactions remaining in the transaction log that aren't yet sent to the Distributor). The result set displays the log sequence numbers of the first and last records for each transaction. sp_repltrans is similar to sp_replcmds, but doesn't return the commands for the transactions.
Remarks
sp_repltrans is used in transactional replication.
sp_repltrans isn't supported for non-SQL Server Publishers.
Permissions
Only members of the sysadmin fixed server role or the db_owner fixed database role can execute sp_repltrans.
