I have a list containing lists of users, at userTask I want each list of users in the list to execute in a predetermined order. and each user in the list executes in parallel. Please suggest me the solution? Thank for all

My list like:

List<List<String>>

Hey @manhld,

In order to be able to help you out we would need to know what you have tried so far. Usually executing things in a predetermined order means you need to use Multi Instance Sequential activities (Service Task, Sub Process, Call Activity, etc.).

Thanks for your reply @filiphr,
I solved the problem with nested sub-processes.
