The way FIBA LiveStats V7 manages substitutions has been completely changed, for the better!
To make a simple one player substitution, scout has to select either SUB button.
When selecting a player who is substituted out, he is added to the Player Off row. When selecting a player who is substituted in, he is added to Players On court row.
Substitution action then appears in Action Log list.
When many players are substituted at once, or there is no time to check who was subbed out/in, it is more convenient to use the Wave Sub functionality: the caller simply calls five player who are on the court and all relevant substitutions are made automatically by system.
To use the Wave Sub functionality in substitution window, user has to click either "Switch to Wave Sub" button.
After that all players from the Players On court row are removed and added to Players Off row.
User then selects new five players and they are added to Players On court row. Players Off row will then display players who were subbed out.
Action Log list will show substitution actions only for players who were subbed out/in.
