Bug 22301007 fix ignores setting in BUS_UNIT_OPT_EX

In order to improve the process of approving expense reports for the users who are currently forced to budget check expenses before they can approve them and this adds a delay to the process as they have to wait for it to complete before they can approve - PeopleBooks suggests a way in which you can disable the requirement for budget check before department managers approve whilst leaving commitment control turned on.

So having disabled the requirement and batched up a budget check process for expense reports so eligible expense reports are checked overnight en masse to take this manual process away from the users we now find that if the approver changes the accounting date it goes awry and requires them to do a manual budget check!
