Comparing Lists: if list1 item exist in list2 then ignore function else perform?

[whoami 26]

Hi guys..

Im trying to create a logic:

 

Im trying to compare between 2 lists..

One list is loaded everytime the program opens, and that list is being used as reference for logs.

Im logging data like usernames so we dont repeat interactions.

 

So technically I need to compare list1 with list2 (fresh and recent)

So if data in list2 exist in list1, then ignore an action. Else then perform action required.

 

Really struggling with this.

I think there are 2 things you can do to accomplish what you want...

 

You can either subtract the lists so you only get unique records by doing something like this:

add list to list(%uniquelist, $subtract lists(%list1, %list2), "Delete", "Global")

or, you can check the list as you go like this:

add item to list(%list1, "test", "Delete", "Global")
add item to list(%list2, "test", "Delete", "Global")
set list position(%list1, 0)
set(#current_item, $next list item(%list1), "Global")
if($contains(%list2, #current_item)) {
    then {
        alert("list 2 contains item from list 1")
    }
    else {
        alert("perform action required")
    }
}

Hey thanks! Just read it, I will analyze that logic inside my program and let you know how it went
