I trying to load incrementally the last 7 days created/updated/deleted data for :
as far as know, there attribute LastUpdateDate but unfortunately not present in all object here above.
is there any other way to achieve this ? is lookback API the solution to this ?
For the Artifacts that do not have a LastUpdateDate Attribute, you may be able to parse the Revision History. See this KB: Query Revisions in WS API - CA Knowledge
