We have 2 tables in One Identity namager: Person and Locality.
We want that Person table etrieve "City", "Room", "Phone" fields from Locality table (from which locality the person belongs).
Any idea how to do this?
Interesting question.
Out of the box, there are templates on the columns Person.City, Person.Room and Person.Phone that fetch the data via the primary location assignment of the person (Person.UID_Locality).
So I think you just need to check the columns in Designer to see if any customizations prevent your use-case from working.
