I worked in MIGO exit 'EXIT_SAPMM07M_001' which have include ZXMBCU02. I Activated it also.
I write a code break abapdev(our user) in include ZXMBCU02. break is working in QAS server but in PRD this break is not working although break code is showing in PRD include also.
Due to above problem I am unable to implement the new functionality .
