Hi Team,
What data type should be used if I want to store the data like this
id,users
1, user1
2, user1; {user2,user3}
3, user1; {user2,user3}; user4
Operations:
We can remove the users from list
input: id, username -> 2,user1
output: 2,{user2, user3}
input: id, username -> 3,user3
output: 3, user1; {user2}; user4

In that actual format you posted, only text will work.
But as discussed in your previous thread - https://community.appian.com/discussions/f/new-to-appian/29769/text-logic - I would recommend not storing users in this format which has nested lists. You should flatten that list and just store a list of users as suggested by Stefan.
