Moving a match to a different court or time doesn't mean you have to regenerate the whole schedule. In Slams you move individual matches with precision, while the standings and the rest of the schedule stay in place. How you do this depends on the format: a tournament and a multi-day event have a visual day-schedule planner, while a league is handled per playing round and per match.
The day-schedule planner (drag or tap)
For a tournament you'll find a grid of courts against time slots under the Day schedule tab. Each match is a card. You drag a card to another court or another time slot, or you tap a match and then tap its new spot (handy on mobile). If you want to swap two matches, you exchange them in one move. The planner writes the new court and start time immediately. For a multi-day event with a shared schedule, the same planner sits under the Schedule tab on the event itself, so you can move matches across the days. There's more background at the day-schedule planner.
The courts you see in the grid come from the court settings of the part. If you want to play on different court numbers, for example courts 2 through 5, change this under setting up courts. A court change like this automatically flows through to the schedule, the court QR codes and the print.
Conflicts are flagged, not blocked
As you move things around, Slams watches along live and flags possible problems. Think of a court that gets double-booked, a team that would be on two courts at once, too little rest between two matches of the same team, a team that is unavailable at that time, or a knockout match that falls before the earlier round. These signals are warnings: you stay in control and can deliberately leave an overlap in place. You can read more about this at overlapping matches. For the unavailability warning to work, you enter each team's unavailability through the planner.
League: per round and per match
A league runs over playing rounds and has no fixed courts in the planner. In the Schedule tab you set a start and end date per round as a guideline. If you do want to lock an exact day and time for a single match, you can do that per match. You can also move a match to a different round. The standings are derived entirely from the results, so changes like these have no effect on the points.
What you can't reschedule
A match that has already been played (with a result) can't be moved or swapped. If you want to do it anyway, first correct the result via correcting a result and then move the match. Also note: removing courts while rounds already exist is refused, because that would lead to double occupancy. In that case, clear the rounds first and use generating a schedule again. Continuous formats such as the ladder have no fixed court and time schedule to reschedule.
