Import a set of system roles to assign it to an user

Hi everyone, 

I'm new in OIM and I'm working in a group were we're try to make a migration of IAM solution to OIM 8.2.

One problem we're facing, is import system roles of an user (which are listed in the csv file) and map them to the same user in OIM.

I read that it is possible using PersonHasESet table, but I don't how to user it to map many systems roles at the same time with the synchronizer. If someboby can give us more information about how to do that, it will be a big help for us.


Thanks for all your response.
