SAP MM 物料主数据里的‘Packaging Material Type'字段
1， 这个packaging material type不是我们通常物料主数据里的material type, 而是在包装物料主数据的’Sales:general/plant’这个视图里出现的一个字段，
事实上，这个包装物料的物料类型是ZERP,
Packaging Material Type
Procedure
Enter a code and a description for a grouping of similar materials, such as crates, trucks or pallets.
Use
The packaging material type that you enter here is linked in Customizing to a material group for packaging materials, which you assign to a material in the material master. As you assemble the handling unit, you call up a list of packaging materials that are allowed for an item that you want to pack. This system puts together this list by matching the material group for packaging materials for that item with the appropriate packaging material types.
Example
During packing, when you call up the list of allowed packaging materials for a material defined in the material master as material group 0001 (beverages), the system lists all packaging materials of type 0010 (barrels) and 0020 (bottles). For group 0002 (small parts), packaging materials assigned to types 0030 (boxes) and 0040 (plastic bags) would be proposed and for group 0003, packaging materials of types 0050 (containers) and 0060 (trucks) would be proposed.
2，物料主数据里的Packaging Material Type, 在SAP后台如下地方配置：
3，这个字段唯一的用处就是通过后台的配置，结合物料主数据的字段‘Material Group: Packaging Materials’一起来使用。
这样在相关打包(Packing)界面，当我们输入要打包的物料号后，系统能根据该物料主数据Material Group: Packaging Materials字段值，根据后台配置建议合适的包装物料（packaging materials）。
4，Packaging material type只需要为包装物料(packaging materials)指定。事实上，在正常的物料比如原辅料等物料主数据里，packaging material type一般都是空的，
