Hi @Sharonmw1
UPDATE (May 2017): Since this post was made a detailed ledger report was added to the Chart of Accounts screen. You will find this by clicking the Export button.
Backing up is the correct way to generate this report. Because of the size of it, we include it as part of an on-demand back up, rather than the automated ones.
If you go into the back up settings (Account Settings >> All Settings >> Weekly / Monthly Back up Schedule), you’ll see an option to run it now. It does take a few minutes to generate, but this will then be delivered by your chosen method (email or dropbox)
There’s a more detailed explanation here.
Hope that helps!
