Warning message issue

Hi,

I am facing a unique issue. In the development system all the warning message for the Z- Message class are shown correctly but in the q-system , only the standard warning messages are shown . Not the Z message class messages. I debugged the issue. In the q system the Z message is processed correctly by the FM CRM_MESSAGES_COLLECT. I am not sure what is going wrong in the system. I am posting a picture of the debug mode in the Q-system for the Z- message class.

Step 1  - : Debug Mode for the handle_message_list class

Step 2 -:  This step shows what my internal table error list contains . One standard warning and one z warning .

Step 3 -: Outcome of the CRM_MESSAGES_COLLECT function module . sy-subrc = 0

Even after this i just see the first standard warning message in the UI. Not the Z class. Is there any customizing by which the z messages are restricted or number of warning message are restricted. Everything works fine in the dev environment.

If any body has an ide please let me know ?

Thanks

Sanket
