Why Do Monthly Totals Change After a Late Transaction Arrives?

Reports may restate a prior month when a source system records a transaction after the period closed. Whether that is correct depends on the reporting rule and close process.

What to check

Check event time versus processing time, the report cutoff, late-arrival policy, refresh history, and whether corrections are included in prior periods or the current period.

Recommended next step

Agree on a restatement rule and show when data was last updated. Informatix Systems can help define analytics metrics and reconcile data pipelines.
