Question:
How Event Speakers are sorted within invitation documents that are created from the EM Events?
Answer:
In case of having more than one Event Speaker on an Event, the related token is retrieving the records ordered by the Last Name value.
The sort order stays even if the token list from the template does not contain the Last_Name_vod field. This is queried automatically as it is hard coded.
