HI James and Simha,
I think u r answer is wrong,please check once.

as per my knowledje,the query is
SELECT E.*,M.MSAL FROM TABLE_NAME E,(SELECT MAX(SAL) MSAL
FROM TABLE_NAME) M;

IF U R SOURCE IS FLATFILE,U NEED TO GO FOR BELOW MAPPING.

SQ----->TRG_TABLE
|
|---->AGG(MAX(SAL))--->TRG_TABLE(MSAL)
IN THE ABOVE DFD IS
1 SOURCE TO TARGET DIRECT MAPPING ALL COLUMNS EXCEPT
MSAL COLUMN.
2.IN THIS DFD FIND THE MAXSAL AND LINK TO IT MSAL IN
THE TARGET TABLE.

IF THERE IS ANY WRONG PLEASE CORRECT ME.

THANKS,
Babu
