You may need to build a query based on whether a transaction is marked as final or not. When something is marked as final it means that only Admins can make changes to the transaction.
This is where the Final checkbox is located on the journal entry.
If you wish to use this Final box as criteria in a query, whether you want to find final transactions or non-final (pending) transactions you can add the query criteria "Journal Entry Status" which is located under the Browse Fields category under Journal. The image below shows it being used in a query.
If you select the Pending radio button the query will pull non-final transactions.
