    Dear DOLEARY85 ,
    I have tried and some old names still because of FIRSTNONBLANK function I think.
    So, I tried with LASTDATE function of Order date and it gave me the expected results.
    Pbix file is not able to share for me.
    So, Please check the screenshot and let me know your thought.
    Thanks a lot for your help.

     

     



    Best Regards,

Yes, both customer id and customer names are the blank
becuase of some manual invoicing.
I'd like to ignore the customers for those invoices. Thanks.

Sorry i think i may have misread what you wanted, so if you wanted another version of the table with those 5 fields but without blank customers you could summarize a new table:

 

Table 2 = FILTER(SUMMARIZE('Table','Table'[CUSTOMER ID],'Table'[CUSTOMER NAME],'Table'[ORDER DATE],'Table'[ORDER ID],'Table'[SALE AMOUNT]),not('Table'[CUSTOMER ID]=""))
 
which changes:

    Dear DOLEARY85 ,

    Actually I only want two columns with Customer ID and Custoumer Name
    Where both are not blanks.
    The below code are nearly working properly but some customers still getting old name.

    FILTER(ADDCOLUMNS(
    DISTINCT('Table'[CUSTOMER ID]),
    "Customer Name", CALCULATE(FIRSTNONBLANK('Table'[CUSTOMER NAME],CALCULATE(MAX('Table'[ORDER ID]))))),NOT('Table'[CUSTOMER ID]=""))

    I think it is better to filter the max Order Date than Order ID because
    some reversal sale comes by larger order ID. Thanks.
    Please help again.

      Okay, it's an easy change then, just change Order ID to Order Date and it'll work the same way:

       

      New Table =
      FILTER(ADDCOLUMNS(
      DISTINCT('Table'[CUSTOMER ID]),
      "Customer Name", CALCULATE(FIRSTNONBLANK('Table'[CUSTOMER NAME],CALCULATE(MAX('Table'[ORDER DATE]))))),NOT('Table'[CUSTOMER ID]=""))
