R3482

-- ============================================================
-- Program: R3482 MRP/MPS Requirements Planning — the batch job that runs single-facility MRP/MPS, netting forecasts, sales orders, and on-hand supply into time-phased plans and action messages.
-- Purpose: MRP/MPS Requirements Planning — the batch job that runs single-facility MRP/MPS, netting forecasts, sales orders, and on-hand supply into time-phased plans and action messages. — auto-generated boilerplate from program-table-map
-- Grain  : F3411 × F3413, F3412, F3460, F4102, F4801 — 1:N joins yield one row per detail line
-- Tables : F3411, F3413, F3412, F3460, F4102, F4801
-- Notes  : Auto-generated skeleton. Julian dates are converted to DATE and implied-decimal amounts are scaled (verify decimals in F9210). Audit columns (…USER/…PID/…UPMJ) are omitted — see the quirks guide. Set catalog/schema to your Unity Catalog location; fill remaining placeholders (<...>) for your tenant.
