Finding Fee Transactions Marked Off Invoice

There is not a report you can run, but you may go into Time Manager and set a date range (transaction date range) to capture fees billed during the month about which you are concerned.  For example, invoices just recently generated in August probably included time worked in June or July.  In your filter, choose Billed Status only.  Make sure you are looking at all Timekeepers and all Entry IDs.  Make sure the Off Invoice field is showing in your grid (right click, choose Select Grid Fields and drag the Off Invoice object to the column headers). Before setting your filter, you may want to check that your limit of the number of transactions that can be displayed is not too low.  To do that, choose TOOLS, Maximum Records.  Increment the number to something high enough that you think all transactions existing in the date range are displayed.
