How to enable expense to have chart of account validations setup in GL security rules?

Hi,

We have created new GL security rules for chart of account combination in Oracle but the expense report do not considering this rule.

When user creating expense report with an invalid chart of account combination, system still allow user to submit the expense.

After submit, the expense report status changed to "Pending System Administrator Action".

Can anyone advise on the solution or if there is any steps missed.

Thank you.
