Steps
Extract per-selection sales counts and revenue from PA1 (selection/price) plus PA7 (cumulative vends per selection since reset/initialization).
Extract total cash sales value and vend counts since last reset from CA1/CA2 for reconciliation against physical cash collected.
Extract cashless sales value/count from the DA2 segment (cashless device 1) to reconcile card/mobile payments against processor settlement reports.
Cross-check EA-series (event/error) segments for outages or resets that could explain sales gaps or counters resetting mid-period.
Sum PA-level product sales and compare the total against the CA/DA aggregate cash-plus-cashless totals to catch parsing or timing discrepancies.
Known gotchas
'Since initialization' and 'since last reset' are two different counter baselines in the same file — reconciliation logic must pick the correct one consistently or totals will not tie out across periods.
Cashless sales appear in DA-series segments (per cashless device slot, e.g., DA2 for cashless device 1) separately from CA cash segments — a reconciliation that only reads CA records will under-count machines with cashless readers.
Vend counts/values reset on VMC resets (power loss, service resets), which can make period-over-period deltas negative or nonsensical unless the reconciliation process accounts for reset events from the EA-series records.
