If you want to set the RoleName based on the value of Group, then I would do the following. Assuming that the Group value is of String.

I named My example entity DataImport

  1. Iterate over the list
  2. Check on the first possible value
  3. If true, set RoleName accordingly
  4. If false, Check on value 2
  5. … etc
  6. Commit the changed list after the loop

 

By the way, if you want to set the USERROLE for accounts in order to login in. Take a look at this learning path to understand how ACCOUNTS can be created automatically; https://academy.mendix.com/link/module/325/lecture/2498/8.7.1-Creating-Accounts
