Hi Renae_dbkacc
I would recommend ensuring that you are using the same accounting method on both those reports i.e. you would need to ensure that the Accounting method selected on the Account transactions report is Accrual (General Ledger by default should be an accrual-based report).
If those accounting methods are the same, I would be comparing the detail to those accounts to identify what transactions are not being included. Once you have located that information getting a screenshot of one of the transactions and a copy of the reports would be required for further investigation.
