BADI不能激活的原因

新定义的BADI:ZMD_MODIFY_PRODVERS不能被激活，一看，原来定义不是Multiple use的，其引用的BADI定义名为：MD_MODIFY_PRODVERS，到表：SXC_EXIT一查，原来系统已经实现了一个实例IMPL_IPPE_MRP_PRODV，并且激活了，因为是非“Multiple use”的BADI，把IMPL_IPPE_MRP_PRODV取消激活，自己定义的这个就可以激活了。

 

 

 

 

Multiple Usability for BADI Definitions

Multiple use for means that there can be several active . When there is a call, they are all called up - however, in an unpredictable sequence.

If you have multiple-use , the sequence must not play any role therefore. A typical example is the execution of checks before a save.
