    Hi mmh 

    You can try the following code:

    New Customer = var _filter=FILTER('Table',[Customer_id]=EARLIER('Table'[Customer_id]))
var _indate=MINX(_filter,[valid_from])
var _end=MAXX(FILTER(_filter,[valid_from]=_indate),[Valid_to])
return IF([valid_from]>=_indate&&[Valid_to]<=_end,"Yes","No")

    Output

    Best Regards!

    HI Yolo,

    Thanks! But its not correct.  Actually here some new customer having two records as like
    Intials date n approved date , so it would be identified as new customer  in both records

    Customer_idvalid_from Valid_toNew Customer
    2021-1-1800  1-1-3000    Yes  (its intial date)
    2021-1-20231-2-2024Yes  (its approval date)

     

    Otherside some customer having record as like

    Customer_idvalidFrom ValidtoNew Customer ?
    1011-1-2020 1-2-2021Yes
    1012-1-2021 3-1-2022  NO
