Why is CREATE_OBJECT_CLASS_NOT_FOUND ?

Dear Guru ,

I am facing a problem that the BADI class can not be executed in our Quality system . When user trigger the badi , it showed us below shortdump :

Runtime Errors         CREATE_OBJECT_CLASS_NOT_FOUND
Exception              CX_SY_CREATE_OBJECT_ERROR
Date and Time          2010.07.16 16:11:05



 Short text
     CREATE OBJECT: The class "\CLASS=ZCL_IM_IMP_BADI_MM_CHK" was not found.



 What happened?
     Error in the ABAP Application Program

     The current ABAP program "CL_EXIT_MASTER================CP" had to be
      terminated because it has
     come across a statement that unfortunately cannot be executed.

I don't understand why this happen after i tranferred the request to quality system .

When i check the class via 'SE24' tcode in quality system, it said :

Class ZCL_IM_IMP_BADI_MM_CHK	5	@0A\QError@
INCLUDE report "ZCL_IM_IMP_BADI_MM_CHK========CL" not found		

But when i checked the class in development system , everything is fine . I can't find above error message .

Could you mind to tell me the reason why this happen and how to solve this problem ?

Many thanks !!

Best Regards,

Carlos
