Merging rules for Multi Select-Address
Need your help to understand merging rules for the Extension field(Multi-Select) available in Address Object.
We have a case where extension is created via Custom object as multi-select in Address.
At Merge, the system should merge this field as well & should select all values available in this field.
Customer ABC - Custom filed Value - 123ABC
Customer ABC1 - Custom Field valve - 456XYZ
Customer ABC - Custom Field - 123ABC & 456XYZ
Is there any standard way or Groovy way to update the field after Merge?
