I don't know where i copied this from, i think from
@legend62009.
1)
activeteams : Not an important table at all, just has 64 entries, idk why
2)
advancement : details which teams (or league positions or cup tie winners) advance to which stage or which competition
3)
compids : id of every competition, not needed to change unless you change the next compdata file
4)
compobj : sets compids for each competition, sets number of matches per stage, sets number of stages and their types, for example, it defines whether it’s a league competition or a cup competition (and subsequently sets its stages) Very important but also very confusing and time consuming
5)
dataver : not important at all, just the version of compdata
6)
initteams : dictates the initial teams in the first season in career mode (change it if you wanna change stuff like super cups or which clubs for example enter from the third round of the efl cup instead of the second round, which clubs are in champions league first season, etc.)
7)
objectives : what stage or position of a competition is needed to mark the objective as successful
8)
schedule : sets the schedule for matches for every competition, like which matchday is it, which day does it happen, at what time does it happen, how many matches are supposed to occur at that time, etc. for each competition
9)
settings : determines the settings for each competition, such as the rules, prize money, what stagetype is it, which nation is this competition for, promotion and relegation, qualification for continental competitions, etc. VERY IMPORTANT TABLE, probably the most important one, with compobj in second
10)
standings : number of teams in a competition stage or a league, so basically edit this table if you want more teams in a league
11)
tasks : tells the game what to do at the start and at the end of a competition, such as which teams, leagues, or nations are in it. Very important if you’re editing continental competitions, otherwise not really
12)
weather : self explanatory
