If there is no sort order, use the Go To Record/Request/Page script step, and set it to last. If this is in list view and you only want to see this record. Then you can use:
Go To Record/Request/Page [Last]
Show Omitted Only
Another method that may give better performance:
Show All Records
Go to Record / Request / Page [ First ]
Omit Multiple Records [ No dialog ; Get ( FoundCount ) - 1 ) ]
Forgot to put Show All Records. Whoops...
