Flag rows in Visual workspace
Add a true/false column that marks rows matching a condition, keeping every row.
When to use it
Unusual but possibly legitimate values that need human review.
How
Add step → Rows → Flag rows. Name the new column and set the condition.
Flag needs_review where amount > "5000.00"
- Comparisons with a missing value are false.
Pitfalls
- Deleting or capping instead of flagging.
- Getting the boundary wrong (> versus >=).
Lesson: Flag outliers, don't delete them
Practise it: Flag large transactions, keep refunds
