If you use account groups in General Ledger, you must assign every account to a group.
Note: The system assigns the Unclassified account group to accounts that use a blank account group code.
To add your own account groups:
General Ledger > G/L Setup > Account Groups.
The code can consist of alphabetical or numerical characters, or a combination of both.
The standard account groups are numbered 01 to 26. You can continue the sequence, or create a different set of codes.
