如何激活SAP库存地点间转储时确定发货库存地点的BADI

在使用库存地点转储功能时，我们需要定义自定义的特殊采购类型，然后BADI通过自定义的特殊采购类型来确定发料库存地点。
但在新建BADI后，却无法激活BADI。

参照下列NOTE激活自定的BADI：
Note 961535 - Active BADI implementation /ISDFPS/MD_EXT_SUP

Deactivate the implementation /ISDFPS/MD_EXT_SUP manually:

1. Call transaction SE37 for function module SXE_IMG_IMPL_ACTIVITY_TOGGLE and choose the function "Test Function Module (F8)".

2. Enter /ISDFPS/MD_EXT_SUP as value for the parameter IMP_NAME and choose "Execute(F8)".

3. In the subsequent dialog box, confirm that the implementation is to be deactivated.

4. Choose or generate a transport request to transport the changes.
