When you memorise a report, it allows you to save it with its current customisation settings.
The memorised report appears on the My Custom Reports list.
If you change the customisation on a memorised report, you need to memorise it again to save the changes.
Note: You can't memorise a report if you are a "Time Tracking only" user.
QuickBooks creates a new memorised report (it does not overwrite the memorised report that already exists). You must choose a new name for the memorised report. If you want to use the name of a memorised report that already exists, you can replace the report that uses that name when prompted, or delete that memorised report first.
