Rule for stop processing of expected event message

Hi Experts,

I am just wondering which rule/action will fulfill below requirement .

I want to stop processing of event message for one of expected event .

I do not want to stop processing in preprocessing function module as i need to create a error log and trigger alert .

QUIT EVENT MESSAGE PROCESSING rule works for unexpected event only .

1) How to fill NOT_RELEVANT field in table EH_EXPEV.

2) If I populated INVALID_DATA field in preprocessing , will it reach to ruleset to create error log and trigger email .

Thanks in Advance ,

Rajesh
