-- Grain  : One row per PO item with delivery schedule line
-- Tables : EKKO, EKPO, EKET, MAKT, MARA, T001W, T001L, LFA1
-- Notes  : EKKO (header) → EKPO (item) → EKET (schedule lines). Filter LOEKZ <> 'L' to exclude deletion-flagged items. Open quantity = EKET.MENGE - EKET.WEMNG at schedule-line grain.
