The default close calendar

The calendar is configurable for each company. By default:

Day Step Gate to pass
Daily Field data entered and validated; provisional allocation No open critical exception older than 24 hours
M+1 Month-end gauges, last tickets, provings Every measurement point has a closing reading
M+2 Gas analyses and heating values; meter-factor review Meter-factor deviations resolved
M+3 Final allocation run; factor band review Factors inside the band, or explained
M+4 Reconciliations Differences under materiality, or explained with evidence
M+5 Entitlements, lifting balances, fiscal quantities Balances agree with terminal stock
M+6 Maker-checker approval and period lock Approver is not the preparer; checklist complete
M+7 onwards Regulatory and partner reports from the locked period Report hash matches the lock

Controls behind the lock

  • Segregation of duties: entering, approving, locking and reopening are separate permissions, and nobody can approve their own entries.
  • Period lock: a locked period is read-only at the API and in the database, and its lock records a SHA-256 hash of the posted records. Reopening needs a second approver and a reason.
  • Prior-period adjustments: the original records stay. The difference posts to the open period, and the affected reports and partner statements are listed for refiling.
  • Completeness: a period cannot lock with missing readings unless each gap has an approved estimate and its method.
  • Audit pack: one export per period with the inputs, rule versions, runs, approvals and audit log.
