Budget checking at Department Level

Dear Experts,

Currently we have have budget check happening at Account level. But we wanted to make it at Department level and not at account level.

For Example- We will pass a budget journal for department 100 with 3 accounts as account is mandatory to pass journal. Later in the main transaction budget check process should not mark the transaction to error till the entire budget at department 100 is consumed.

Please advice the possible ways that we can bring the budget checking to dept level than account level.

Regards,
