Hi Alessandro,
May I ask you if I can consider using "Custom Fields".
First of all, I think that the field I am trying to map from HR is not standard field (Please correct me, I an not sure and this is just my guess).
If lets say it is not standard, then I think custom field is to be used. Next question is that, if I use custom field, then how I can make 'validity to' of roles to this custom field?
Please suggest/advise.
Regards,
Faisal
