Calculated column aggregating its own table

"Calculated column aggregating its own table" is one of the performance checks Auditabi runs on a Power BI semantic model. n calculated column(s) aggregate the table they belong to without CALCULATE. It is a medium-severity finding: the model still works, but results are wrong in some filter contexts, slow, or fragile under change. Use a measure, or wrap the aggregation in CALCULATE when a per-row total really is intended.

What is detected

n calculated column(s) aggregate the table they belong to without CALCULATE. The aggregation ignores the row context and returns the same grand total on every row — and it is computed at refresh for every row.

Why it matters

Wrong in some filter contexts, slow, or fragile under change. Fix in the next iteration.

How to fix it

Use a measure, or wrap the aggregation in CALCULATE when a per-row total really is intended.
