how do you know which is which?  is there a date column, or is it the first in line?

if first inline you can create a index column to extract the data out, if you can provide the data in text format, not a picture that would be good and i can demonstrate.  easier with data.

@vanessafvg - There is no date with the table. All the records was parsed on JSON and expanded address resulted to the table above. When i look at the json structure, the first is the current address.

Hi @Anonymous 

what is the rule to define the current address? any indexes or dates or smth else?

@az38 - there is no rule that define current address. The table was parsed on JSON, no index, no date.

ok so if there is no rule, what is the rule you want  to select the data, just the first one in sequential order? 

I would add an index in the transformation layer (power query), under add column / index column

and then create a dax measure

addressstatus =
VAR person =
    SELECTEDVALUE ( 'table'[fullname] )
VAR currindex =
    SELECTEDVALUE ( 'table'[idcolumn] )
VAR minid =
    CALCULATE ( min ( 'table'[idcolumn] ), 'table'[fullname] = person )
VAR status =
    IF ( currenindex = minid, "Current Address", "PreviousAddress" )
RETURN
    status
