How to write condition logic in message mapping??

Hi <Removed by Moderator>,

    Can you please let me know how to write a condition logic in message mapping?

    I need to write a logic to exclude entering into message mapping if one of the fields in message mapping contains

    a string called "TEST". Which means i should not enter into the message mapping if the field has value "TEST" in one of the fields

    from message mapping; Hope you got my point. Any help appreciated? Thank you.

Regards

Rupa
