Classify Busy Entities into ABC Contribution Tiers
busy_abc_classification
Read-only
How it behaves
Use this when the user asks to classify customers, products, direct groups, material centers, states, salespeople, or values of one compatible configured customer/product field into A, B, and C contribution tiers for one Busy period. Resolve configurable labels with busy_get_dimension_catalog and pass the canonical key in dimension; never guess OF1-OF10 meanings. It ranks positive eligible values by gross sales, sales returns, or return-adjusted net sales and keeps equal-value ties together. Keep entity_type for legacy populations. Do not use it for quantities, gross profit, company, time, supplier/purchase, branch/territory, forecasts, or transaction drill-down. Use busy_pareto_analysis for arbitrary thresholds.
