MSC_SYSTEM_ITEMS

-- ============================================================
-- Table  : MSC_SYSTEM_ITEMS — The planning copy of the item master at plan + instance + org + item grain — collected item attributes frozen per plan run, and the bridge column back to the source EBS item
-- Purpose: Column-selected read of MSC_SYSTEM_ITEMS — auto-generated from field metadata
-- Grain  : One row per inventory org (ORGANIZATION_ID) + PLAN_ID + SR_INSTANCE_ID + INVENTORY_ITEM_ID
-- Caution: INVENTORY_ITEM_ID here is the planning-side surrogate — the EBS item id is SR_INVENTORY_ITEM_ID; the single bridge edge uses that item pair plus ORGANIZATION_ID to prevent fan-out and assumes one collected source instance
-- Notes  : Auto-generated skeleton for Oracle EBS R12 data landed in your lakehouse. Dates are real DATE/TIMESTAMP columns — no conversion needed. WHO audit columns omitted (see the quirks guide); the optional LAST_UPDATE_DATE watermark filter supports incremental extracts.
