yes want to do separately.thanks for your comments  
You would require two INSERTs and an UPDATE
Just convert my MERGE into INSERT and UPDATE 
Use a further INSERT over the UPDATE
ie like below
INSERT Supplier_Dest
Supplier_Code,
Supplier_Name,
Current_State,
Historical_State,
Start_Date,
End_Date,
Current_Flag
SELECT Supplier_Code,
Supplier_Name,
Current_State,
Current_State,
GETDATE(),
'99991231',
'Y'
FROM
UPDATE d
SET Current_State = s.Current_State,
End_Date = CASE WHEN d.Current_Flag = 'Y' THEN GETDATE() ELSE End_Date END,
Current_Flag = 'N'
OUTPUT INSERTED.Current_State,
INSERTED.Supplier_Code,
INSERTED.Supplier_Name,
INSERTED.Start_Date
FROM Supplier_Dest AS d
INNER JOIN Supplier_Source AS s
ON s.Supplier_Code = d.Supplier_Code
AND COALESCE(d.Current_State,'') <> COALESCE(s.State,'')
)t(Current_State,
Supplier_Code,
Supplier_Name,
Start_Date)
WHERE Start_Date <> '19000101';
INSERT (
Supplier_Code,
Supplier_Name,
Current_State,
Historical_State,
Start_Date,
End_Date,
Current_Flag)
SELECT
s.Supplier_Code,
s.Supplier_Name,
s.State,
s.State,
'19000101',
'99991231',
'Y'
FROM Supplier_Source AS s
WHERE NOT EXISTS (
SELECT 1
FROM Supplier_Dest
WHERE s.Supplier_Code = Supplier_Code
AND COALESCE(Current_State,'') <> COALESCE(s.State,'')
