Hi
Teacher tm,km,hm teach History geography and business study at 11a,11b,11c at the same time
we need this period to appear before 12:00 every day
tm,km,hm = hist/geo/bus
from lavert
use one of the preferd time constraints.
(if you are not shure, then add a tag to this activities and use preferd times constraint for that tag)
how, show me step by step
from Lavert
this is the solution with activity tags. maybe it is possible with an other constraint, but i don't know you excact dataset. so this version is maybe not the fastes to enter, but is also working if you can't use one of the other constraints:
fet -> data -> activity tags
add an new activity tag. maybe call it "before 12"
fet -> data -> activities (or fet -> advanced -> activity planning)
modify all activities that must be before 12 o clock. add to all of them the new activity tag.
fet -> time constraints -> activities -> a set of activities has preferd starting times (day + hour)
add a new constraint.
set in the upper right coner the new activity tag "before 12" and disable in the table grid all hours after 12 o clock.
then add this constraint.
