Optimize app formula expression

[Saifabbs]

I have an app formula to get the ref rows in a virtual column. I noticed the load time increased after implementing it—is there any way to optimize the formula?

List(Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Admin")), 1),
Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team 1")), 1),
Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team 2")), 1), Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team 3")), 1), Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team 4")), 1), Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team 5")), 1), Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team 6")), 1), Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Team DXB")), 1), Index(Select(Link[Invoice], And([_THISROW]=[Event Code], [Team]="Teamless")), 1))

 There is tons of redundancy in this and is calculated for each row which is not needed.

I'm not quiet sure what you are trying to actually get at, but your use of Index with Select and then constructing a list out of individual records is your main problem. I'm not sure if this will solve it for you but give it a try:

SELECT(Link[Invoice], AND([_THISROW] = [Event Code], IN([Team], {"Admin","Team 1","Team 2","etc")))

I would like to get just one row where the team name matches.

Using the expression you provided:

This is a virtual field I use to show the amounts for each team. I would like the result to be similar to this: 

I tried to apply a row filter to get just 1 row for each team but couldn't get the correct expression for it,

Looks a bit like you are trying to construct a pivot table summary. I personally have not implemented something like this in Appsheet but I thought others have put together some sort of documentation.
