Hello,
I'm trying to use below code to find the last Invoice number (Highest) per client.

Results I'm getting is all Invoices / per client.

Can you please help.

Select (Select Name From Clients where Clients.AccountNumber = AROpentransactions.AccountNumber) AS [Client],
AccountNumber, MAX (TransactionDate), TransactionNumber,OrdersSubtotalAmount,SalesAmount,TaxAmount,ARAmount,
(Select Accountlocked From Clients where Clients.AccountNumber = AROpentransactions.AccountNumber) AS [Accountlocked]  
from ARopentransactions
where (Select Accountlocked From Clients where Clients.AccountNumber = AROpentransactions.AccountNumber) = 1
AND TransactionType = 1
GROUP BY AccountNumber,TransactionNumber,OrdersSubtotalAmount,SalesAmount,TaxAmount,ARAmount

Thanks,

forgot an entry in that query (line 15)
SELECT
      Clients.NAME AS [Client]
    , OT.AccountNumber
    , OT.TransactionDate
    , OT.TransactionNumber
    , OT.OrdersSubtotalAmount
    , OT.SalesAmount
    , OT.TaxAmount
    , OT.ARAmount
    , Clients.Accountlocked
FROM ARopentransactions as OT
INNER JOIN (
            SELECT
              AccountNumber
            , TransactionDate
            , row_number() over (partition by AccountNumber order by TransactionDate DESC) as row_ref
            FROM ARopentransactions
            WHERE TransactionType = 1
           ) AS Latest ON OT.AccountNumber = Latest.AccountNumber
                      AND OT.TransactionDate = Latest.TransactionDate
INNER JOIN Clients
        ON  OT.AccountNumber = Clients.AccountNumber
WHERE Latest.row_ref = 1

is there a unique row identifier in table ARopentransactions? if there is this would be more efficient
SELECT
      Clients.NAME AS [Client]
    , OT.AccountNumber
    , OT.TransactionDate
    , OT.TransactionNumber
    , OT.OrdersSubtotalAmount
    , OT.SalesAmount
    , OT.TaxAmount
    , OT.ARAmount
    , Clients.Accountlocked
FROM ARopentransactions as OT
INNER JOIN (
            SELECT
              ID --<< unique identiry of this table
            , TransactionDate
            , row_number() over (partition by AccountNumber order by TransactionDate DESC) as row_ref
            FROM ARopentransactions
            WHERE TransactionType = 1
           ) AS Latest ON OT.ID = Latest.ID --<< unique identiry of this table
INNER JOIN Clients
        ON  OT.AccountNumber = Clients.AccountNumber
WHERE Latest.row_ref = 1

I suspect you may find the derived table is just missing the TransactionDate column (but no points if I am right).  In other words, it should be:
SELECT  Clients.NAME AS [Client],
        OT.AccountNumber,
        OT.TransactionDate,
        OT.TransactionNumber,
        OT.OrdersSubtotalAmount,
        OT.SalesAmount,
        OT.TaxAmount,
        OT.ARAmount,
        Clients.Accountlocked
FROM    ARopentransactions AS OT
        INNER JOIN (SELECT  AccountNumber,
                            TransactionDate,
                            ROW_NUMBER() OVER (PARTITION BY AccountNumber ORDER BY TransactionDate DESC) AS row_ref
                    FROM    ARopentransactions
                    WHERE   TransactionType = 1
                   ) AS Latest ON OT.AccountNumber = Latest.AccountNumber
                                  AND OT.TransactionDate = Latest.TransactionDate
        INNER JOIN Clients ON OT.AccountNumber = Clients.AccountNumber
WHERE   Latest.row_ref = 1
