You will receive this error message when the value you entered into the Cost Account in the General Ledger Batch is invalid. You may have mistyped it or accidentally entered a Ledger Account in the Cost Account.
To fix the error, review the line with the mentioned Cost Account and select a valid option. The Cost Account field has a drop-down list, so you can choose from the list instead of typing. You can also use wildcards where appropriate for Cost Accounts. The wildcards are % for multiple characters or _ for a single character.
