# Operations BI Dashboard input and refresh guide

## Required input

Provide exactly one UTF-8 CSV with one header row and at least one data row. The maximum is 10,000 data rows and 75 columns. Include one period or category column for context and one or more numeric columns to total. Remove personal, regulated, credential, payment-card, banking, and government-identifier data before submission.

## Processing steps

1. Export and sanitize the CSV.
2. Confirm the column names and business definitions.
3. Run the registered Operations BI Dashboard workbench.
4. The engine counts nonblank rows and sums columns whose nonblank values are entirely numeric.
5. Compare the reconciliation report with the source row count and numeric totals.
6. Complete the required human release review before delivery.

The engine does not infer KPI definitions, calculate rates or trends, repair semantic errors, or decide whether a result is good or bad.
