I'm looking to find any transactions that were NOT assigned to a project. Orphan transactions. You can run a general ledger report which has a column for "project/Customer" but even if a transaction is logged to a project, it won't show in that column. There doesn't seem to be any report that will allow you to show all transactions with the projects they are assigned to. Only reports on a single project which won't allow you to see any transactions with no project assigned.
