Analyze Busy Customer-Product Price Realization

How it behaves

Use this when the user asks what effective tax-exclusive price a customer paid for a product, whether realized prices are below or above a selected current Busy product-master price or observed product median, or what revenue variance follows, optionally filtered or summarized by a product field resolved with busy_get_dimension_catalog. Product filters apply before medians and price metrics; never guess configurable-field meanings. It returns customer-product realized prices, benchmark evidence, per-unit and percentage variance, expected sales at benchmark, signed revenue variance, and the non-negative gap below benchmark. Do not describe the current-master benchmark as the historical authorized voucher-date price, do not treat a negative variance as unauthorized discount or leakage without checking commercial terms, and do not use this tool for cost, gross profit, margin, returns, branch, territory, or causal conclusions.
