    Hi grprem81us

     

    It seems there're two ways. First, you need to use M Language in Advanced Editor. You may refer to this post. Second, you may create a calculate column with Search Function. Show a sample as below:

    Column =
CALCULATE (
    MAX ( Country[Country] ),
    FILTER ( Country, SEARCH ( Country[Phone], Number[Number], 1, 0 ) )
)

    Regards,

      Hi Cherie,

       

      Thanks for your Reply. I tried using the Formula mentioned in your reply. In some cases i am getting wrong output.

       

      For Example the Number was "914842531599" and the result i got was "599" instead of 91.

       

      My Result should be always from the First digit and it should NOT be matching from middle of Number.

       

      Note : my  Phone list had all the number starting with 91XXX and 91. There was NO Phone number list with 914XX.

       

      Thanks

        Hi grprem81us

         

        You may have a look at Search Function. The Parameters 'start_num' of this function will be the mumber which you want to start researching. 

        Column =
CALCULATE (
    MAX ( Table1[Name] ),
    FILTER ( Table1, SEARCH ( Table1[String], Table2[Number], 1, 0 ) )
)

         

        If it is not your case, please share some data sample and expected output.

         

        Regards,

        Cherie
