    Hi, M_BAKOUR_95 

     

    Based on your description, I created data to reproduce your scenario.

    Table:

     

    You may create a calculated table as below.

     

    Compare = 
ADDCOLUMNS(
    SUMMARIZE(
        'Table',
        'Table'[bnf_name],
        'Table'[Wife_name]
    ),
    "NewDate",CALCULATE(MAX('Table'[Date]))
)

     

     

    Result:

    Compare:

     

    Best Regards

    Thanks, but this method does not work
    Because the "compare" table does not appear in the power query and new Table = distinct (Table)
    Also, it does not work because the rest of the values in the rest of the columns are different, and I just want to take the date with the latest date between the matching lines with the name and wife

      M_BAKOUR_95 , Seem like you have an ID column 

      Max Id = maxx(filter(table, table[Name]=earlier(table[Name]) && table[WIFE]=earlier(table[WIFE])
					&& table[Date]>=earlier(table[Date])),Max(Table[ID]))

       

      Now filter

      new Table = filter(table,table[ID]=table[Max ID])
