CO02

-- ============================================================
-- T-Code : CO02 Change Production Order
-- Purpose: Change an existing production order (quantity, dates, operations)
-- Grain  : One row per production order with first-line item and operation
-- Tables : AFKO, AFPO, AUFK, AFVC, MAKT, MARA, T001W
-- Notes  : AFVC joins to AFKO via AUFPL (routing number), NOT AUFNR — otherwise you get a Cartesian product on operations. Status evaluation requires JEST + TJ02T lookup (see JEST trick at end).
