-- Otomatik Ata: stoktan çıkan satırın lot dağılımını kaynak konumun stoğundan ürün kategorisinin çıkış stratejisiyle yeniden kurar
-- (FIFO: ilk giren ilk çıkar, LIFO: son giren ilk çıkar — InDate, aynı anda girenlerde lot/seri no; kategorisiz ürün FIFO). Planlama'nın Öner'i aynı kuralı izler.
-- Stok yetmezse karşılanabilen kadar atanır; eksik Tamamla'da bildirilir.
