Why Do Analytics Reports Show Different Totals After a Late Data Correction?

11/10/2026

A late correction can update source records after reports have already been published. Depending on whether pipelines overwrite, append, or snapshot data, totals may change in only some periods or dashboards.

What to check

Compare correction timestamp, event time, watermark, transformation version, report cache, and historical update policy. Trace representative records through raw, modeled, and published layers.

Recommended next step

Define how late corrections restate history and make the effective data-through time visible. Add reconciliation between source correction counts and changed report totals.
