First you need to retrieve the role you want. You need to retrieve the “System.UserRole” entity from the database and then use this XPath to retrieve the role that you want: (Do this multiple times for multiple roles)
[id = '[%UserRole_USERROLENAME%]']
Then create a list and add all userroles you have retrieved to that list. At the end you can change the account object of the user and set the reference “System.UserRoles” to that list containing all userroles (Picture below).
You can retrieve System.UserRole in the microflow. you can set the XPath to [Name = ‘User’] and a second retrieve for [Name = ‘admin’].
You can then use a ChangeObject to add the retrieved user roles to the account. (note in my example the user role variable is called ‘DeploymentTeam’.
You can either add both user roles to a list and add the list where I have $DeploymentTeam. Or use the Add option in the change object twice, one for each user role.
