Does this report simply look at the modified date on the lead??
If this is the case then it is very possible that the lead has been active
because manya activities could have been added which do not update the
modified date.
Does anyone know how to run a query to search for all leads that
a) do not have any activites set at all (at any status)
b) do not have any activities due from now today forward (this must also
capture those leads with no activities at all).
Many thanks
James
