+# Total Stock Value Report - SSMM
+
+> Net stock quantity and total purchase value per stock item, as of a given date.
+
+## Purpose
+
+Computes the current on-hand stock value for each stock item at SSMM as of a chosen date. It does this by:
+
+1. Summing everything **purchased** (received via external supply deliveries) up to that date.
+2. Subtracting everything **dispensed** to patients up to that date.
+3. Subtracting **mistake adjustments** — stock moved into a configured set of "mistake / correction" destination locations, treated as outflow.
+
+The result is the **net quantity** and **net purchase value** of stock remaining per item.
+
+## Parameters
+
+| Parameter | Type | Description | Example |
+|-----------|------|-------------|---------|
+| `selected_date` | DATE | As-of date for the report. All purchases, dispenses, and mistake entries up to and including this date are considered. | `'2026-05-31'` |

+## Notes
+
+- **`purchase_items` CTE** — external purchases only. Uses `edo.origin_id IS NULL` to filter to supply deliveries that originate from outside the facility
+- **`dispense_items` CTE** — outflow via medication dispenses to patients. Includes dispense orders in `completed / in_progress / draft` and dispenses in `completed / in_progress / preparation` to match what reduces stock in practice.
+- **`mistake_items` CTE** — supply deliveries whose destination is one of the configured "mistake / correction" locations. These represent stock moved out for adjustments and is treated as outflow.
+- **Hardcoded values:**
+  - `edo.destination_id IN (264,270,280,274,273,275,276,266,279,36,265,278,297,238,298,27,481,17,32,277)` — the list of "mistake / correction" destination locations. Update this list whenever new mistake/correction locations are added or old ones are retired.
