How to supress messages generated by BW Queries

Standard Solution :You might be aware of a standard solution. In transaction RSRT, select your query and click on the "message" button. Now you can determine which messages for the chosen query are not to be shown to the user in the front-end.
Custom Solution:
Only selected messages can be suppressed using the standard solution. However, there's a clever way you can implement your own solution... and you don't need to modify the system for it!
All messages are collected using function RRMS_MESSAGE_HANDLING. So all you have to do is implement an enhancement at the start of this function module. Now it's easy. Code your own logic to check the input parameters like the message class and number and skip the remainder of the processing logic if you don't want this message to show up in the front-end.

FUNCTION rrms_message_handling.
Start
ENHANCEMENT 1 Z_CHECK_BIA.
* Filter BIA Message
if i_class = 'RSD_TREX' and i_type = 'W' and i_number = '136'
* just testing it.
* exit
end if.
