QM02

-- ============================================================
-- T-Code : QM02 Change Quality Notification
-- Purpose: Change an existing quality notification
-- Grain  : One row per notification item (QMEL header + QMFE item)
-- Tables : QMEL, QMFE, QMIH, MAKT, MARA, LFA1, KNA1, T001W
-- Notes  : QMEL.QMART distinguishes notification types: 'Q1' customer complaint, 'Q2' vendor complaint, 'Q3' internal. System status is derived via QMEL.OBJNR -> JEST -> TJ30T/TJ02T, not stored on QMEL.
