除了Storage Location和Shipping Point，SAP里面还有Loading Point。
Loading Point is futher Division if Shipping Point.
For example in a Shipping Point there are four gates:
Gate 1 - for Chemicals
Gate 2 - for Perfumes
Gate 3 - for Scrap
Gate 4 - Only for receiving Goods.
Loading Point是Shipping Point的进一步划分，一个Shipping Point可以分成多个Loading Point。
举个例子，假设我们把一个仓库设成一个Shipping Point，这个仓库有三个门，东门主要是发A产品，西门发B产品，北门发C产品，那么我就可以把这三个门设置成这个Shipping Point下面的三个Loading Point。
