In Oracle PPM, do external commitments, internal commitments, and accruals impact budgetary control?

Summary: We have a requirement to incorporate external commitments, internal commitments, and accruals into our Oracle PPM implementation. We are trying to figure out if commitments and accruals have any impact to budgetary controls and your available control budget. From what I can tell Accruals does not as it creates a $0 sum transaction due to the reversal, I believe external commitments does not but we are not sure how to load them in manually to check, and we're not sure on internal commitments. Any help would be appreciated.
