Problem while posting event message through ADDEVENTMSG02

Hi,

I have created an event handler through bapi_eh_post and then tried to post event message through addeventmsg02.

I am facing problem while posting event message through ADDEVENTMSG02.

Sometimes It is working properly and sometimes it won't.

Morever, Both cases are occuring for same entry in TRACKINGHEADER and  TRACKPARAMETERS.

Working Scenario:

The return parameters provide 3 entries.

Non-Working Scenario:

The return parameters provide single entry.

Basically event message for the event handler is not processed in this case, thats why no ruleset is triggered in this case.

Kindly suggest, what needs to be done to mitigate the issue.
