Why 'Message i398(00) with 'Just for a test'' does not work in badi

Dear all :

I got a confusing problem,

In ECC5.0 in badi ME_PROCESS_PO_CUST.

I write the code in method 'PROCESS_HEADER',

METHOD IF_EX_ME_PROCESS_PO_CUST~PROCESS_HEADER.

BREAK-POINT.

MESSAGE I398(00) WITH 'JUST FOR A TEST'.

ENDMETHOD.

It worked well,but i put it into ECC6.0 ,It does't work,

What can I do now?

Thank you very much.
