How does B2R control budget consumption?
Availability control compares the object-specific allowed budget with commitments and actuals so owners can act before an overspend becomes irreversible.
B2R ROLE
Make budget consumption visible before it becomes irreversible
Commitments show likely future consumption; actuals show booked consumption. The report must clearly state which are included.
WORKING FLOW
From request to controlled evidence
Measure the available amount
Use the configured control basis: current budget, released project budget where applicable, or another configured basis less commitments, actual consumption, and any approved adjustments.
Route exceptions to a decision
Warn, block, or escalate according to the object profile and tolerance settings. Resolve the cause through cancellation, rephasing, transfer, supplement, or an approved exception - not by hiding the variance.
Compare consumption and capacity
Use the approved budget, release where applicable, commitments, actuals, and period status to identify risks before decisions become irreversible.
Retain the evidence trail
Keep the source request, approval, release where applicable, change record, control result, owner, and report scope available for review.
CONTROL POINTS
Do not blur these decisions
Plan is not authorization
A working plan or forecast estimates the future. A budget becomes a spending boundary only after the defined approval route and release where applicable.
Actual is not commitment
Booked value and future obligation need separate reporting treatment, even when both reduce the remaining capacity.
Change needs authority
Transfers, supplements, returns, rephasing, and exceptions require the same traceable governance as the original budget.
DIAGNOSTIC EVIDENCE
Trace the position from source to decision
Use the owning object and last trusted record before changing a budget, control, or report.
Object, approved or available authority, period, currency, tolerance profile, and included commitment or actual categories.
New transaction, existing consumption, remaining availability, warning or block, timestamp, and control message.
Cause, owner, cancellation, rephasing, transfer, supplement, or approved exception with its audit trail.
PLANNING MOMENT
A purchase order exceeds available budget
The owner checks whether the difference comes from stale commitments, a late actual, an unapproved change, or a real shortfall. The transaction remains blocked or warned according to policy until the responsible decision is recorded; the report is not repaired by hiding consumption.
- Authority and consumption remain separate
- The source evidence identifies the owning object
- The accountable action is recorded before closure
