At this time, there is no functionality to make accounts inactive in General Ledger.

You can submit an enhancement request from the application Help menu, select Web Resources, Submit Enhancement Request.

TIP 1: You can add "Do Not Use" to the description of unused accounts (Setup, Accounts). Do not delete old accounts. If you delete old accounts with a transaction history, historical reports may not print correctly or appear out of balance.

Refer to How do I retire a General Ledger prefix and full accounts? for information on how to archive old accounts.

TIP 2: You can make the account (Setup, Accounts) a Control Account to stop entries being made in GL. If full Control Accounting is in place, you can select the Type of Control Account to be contra to the application where the account may be selected for use. Refer to What are Control Accounts?
