How to get GUIDs after posting event parameters

Hello All,

I am getting my data from a flat file with serial number, event id and other fields using FM' /SAPTRX/BAPI_EH_ADDEVENTMSG_02' with this I am also updating a Z table with parameters along with guids, but after executing this bapi the return parameters does not return with guids for the events.

Now I have to update another Z table using the same internal table along with GUIDs, could any one let me know how to get the GUIDs for the events I posted.

Thanks,

Kishore.
