I am trying to create a new fields from a multi value fields. Here's an example:
group_id, user_id  user_address         user_phone_number
a         123      cityA, NY, USA       123-234-345
          234      cityBC, NJ, USA      234-345-345
b         567      cityDEF, NY, USA     234-345-456
stats list(user_id), list(user_address), list(user_phone_number) by group_id
user_id, user_address and user_phone_number are multi value fields.
I want to be able to extract state information from user_address to generate a table like this
group_id, user_id  state         user_phone_number
a         123      NY            123-234-345
          234      NJ            234-345-345
b         567      NY            234-345-456
How can I achieve this?
 
		
		
		
		
		
	
			
		
		
			
					
		The same way as extracting it from a single value field:
| stats count | fields - count | eval foo = "New York City, NY, USA;Los Angeles, CA, USA" | makemv foo delim=";" | rex field=foo ", (?<state>[A-Z][A-Z]),"
 
		
		
		
		
		
	
			
		
		
			
					
		The issue is not the expression, that worked fine. Apparently your Splunk version treats multi-valued fields differently.
Updated with (?
foo                                 state
New York City, NY, USA              
Los Angees, CA, USA
 
		
		
		
		
		
	
			
		
		
			
					
		Maybe try a different regex?

		I see. Over here in 5 it works like a charm.
foo                                 state
New York City, NY, USA              NY
Los Angees, CA, USA
CA is not listed
I am using splunk 4.3.1.
 
		
		
		
		
		
	
			
		
		
			
					
		What result are you getting when you enter my example query into splunk?
With this query, if I run
stats list(user_id), list(state), list(user_phone_number) by group_id
I will get this: 
group_id, user_id  state         user_phone_number
a         123      NY            123-234-345
          234                    234-345-345
b         567      NY            234-345-456
Any idea how to get a full list of states?
