UWL showing multiple userids
We have a consumer portal connecting to multiple backend systems and multiple BI portal systems. When I try to forward a workitem and search for a userid, it shows 2-3 entries with the same userid. I am not sure why it's showing multiple entries with the same userid, though userid is unique. Is it picking up the userid from all the systems it's trying to connect?
Please let me know with helpful answers/suggestions.
Thanks in advance
