* 2 => Fetch both packed and loose quantities
* 3 => Fetch only loose quantities
* To determine whether ONLY loose quantities are to be displayed:
* a) Subinventory, cost group for the current record (in QUANTITY_FOLDER block) are not NULL
* b) QUANTITY_FOLDER.PACKED is NOT NULL (for WMS org) and is equal to 0
* c) The current record does not have VMI or consigned stock
* d) For a lot controlled item, the QUANTITY_FOLDER.LOT_NUMBER is not null.
* When the above conditions are TRUE, then call the quantity tree with tree_mode = 3 and default
* the on-hand quantity to :QUANTITY_FOLDER.ON_HAND.
* If the current node has VMI or consigned stock, am showing the entire quantity(both packed and loose)

在计算物料的可保留量的时候，我们通常的做法是MTL_ONHAND_QUANTITIES
中的TRANSACTION_QUANTITY的数量按照组织+物料+子库+货位+批次…的方式
进行累计，然后再减去物料在MTL_RESERVATIONS 中对应的保留。很多的时候没有去考
虑此时库存事务处理接口表(MTL_MATERIAL_TRANSACTIONS_TEMP)中物料数量，这样计算
出来的数量可能会不准确。以下是考虑了库存事务处理接口表的物料数量的计算方
式。大家不妨可以参考一下。
