In this before insert or update Business Rule, we are fetching a reference field value from higher-level parents in hierarchy when there is a field containing the parent record in the children and our use-case reference field is present in all the tables in hierarchy.

In future, use the getter and setter methods (getValue('field') and setValue('field',value) as well as the getValue() method on GlideElements when dot-walking)

This is a "before insert/update" Business Rule We are fetching a reference field value from higher-level parents in hierarchy when there is a field containing the parent record in the children and our use-case reference field is present in all the tables in hierarchy
Through the code we are checking the empty value of the use-case reference field and dot walking to parents and fetching the value from them if it exists
