What is reconciliation after extraction?

< 1 min read

Reconciliation after extraction means validating extracted data matches the source system.
We compared record counts between SQL tables and Power BI dataset.
For finance data, we validated total revenue and transaction totals daily.
Any mismatch triggered investigation before releasing reports.
We used control tables storing expected row counts from source.
Null or duplicate checks were also part of reconciliation.
API extraction verified last transaction ID to confirm completeness.
This ensured no missing or partial data after refresh.
Business users trusted reports because numbers matched source system.
So reconciliation guarantees data accuracy and reporting reliability.
