We have a route schedule, the STT is 48 days, the route is also 48 days, this route schedule works good. This route schedule is used in STO.
Now we change the route days to be 58 days, and also change the STT on route schedule to 58, then route schedule would not be applied on the STO. We change the route schedule STT to be 57 (1 Day less than the route days), it automatically be applied in the STO again.
Experts, could you explain why? why when both are 48 days it works, and both changed to be 58 days, then does not work? it seems nothing else is different, except the days.
