Receipt Accounting Excluded in Budgetary Control

Summary:

Why would the Receipt Accounting journal source be excluded from posting to Budgetary Control?

Content (please ensure you mask any confidential information):

Our OCS implementation consultants excluded the Receipt Accounting journal source from posting to Budgetary Control. We use both encumbrance accounting and budgetary control. The result of this is that the reversal of the un-invoiced receipt accrual was not reflected in Budgetary Control in the first period of the new fiscal year. Budget is now short by that and GL does not equal BC. Is there some valid reason for excluding the Receipt Accounting journal source from posting to Budgetary Control?
