-- Planla diyaloğunun İç Transfer ızgarası (Prc.MaterialRequestPlanSource) ve iç transfer / stoktan karşılama kararlarının stok kuralı:
-- talep kaleminin ürününün stoğu olan iç konumlar. Ürün lot/seri ile takip ediliyorsa satır konum × lottur (seride her seri ayrı satır), yoksa
-- konum başına tek satırdır (LotNo boş). Talebin teslim konumu da listelenir (IsDestination): oraya yazılan plan Stoktan kararıdır (PlanMethod =
-- Stock; kaynağı ve hedefi teslim konumu olan iç transfer açar). Miktarlar kalemin biriminde; ayrılan = açık (Taslak/Bekleyen/Hazır) transferlerde o konumdan istenen
-- (lot satırında o lota atanmış), serbest = eldeki − ayrılan, lot satırında konumun serbest stoğuyla sınırlı (lotu henüz atanmamış istek de
-- konumdan düşer). Plan Miktarı kalemin bu satır için taslak planıdır. BaseId diyaloğun süzdüğü kalem, Id kalem + ':' + konum + ':' + lottur
-- (Prc_P_MaterialRequestPlanLineSave ayırır); taslak kaydı ve onay serbest stoğu buradan okur.
-- AvailableQuantity satırın taslak planda kullanabileceği stoktur (aynı konumun diğer lotlarına yazılmış taslak konumdan düşer);
-- MaxQuantity bununla planlanacak kalandan kalemin diğer taslak satırları düşüldükten sonra kalanın küçüğüdür (ızgaranın doğrulaması; kayıt
-- yordamı aynı kuralı yeniden denetler). RemovalRank Öner'in ve Seçilenleri Planla'nın sırasıdır: teslim konumu önce, sonra ürün
-- kategorisinin çıkış stratejisi (FIFO: en eski giriş, LIFO: en yeni giriş; aynı anda girenlerde lot/seri no — LIFO'da büyükten; kategorisiz ürün FIFO).
