Data Quality and Categorization Pitfalls
Banks often pass cryptic descriptors. One coffee shop appears as CITY-CAFE-001 one day and CAFE CITY 1 the next. Train your system with a few curated mappings, then let a rule apply them. Review weekly exceptions to keep the map tidy without becoming a full-time bookkeeper.
Data Quality and Categorization Pitfalls
