It'd help if you formatted your decode statement.

I just did and got this:

1 ORDER BY DECODE(nvl(UPPER('&&order_by'),party.party_name),
2                 'CUSTOMER NAME',
3                 PARTY.PARTY_NAME,
4                 'CUSTOMER NUMBER',
5                 CUST_ACC.ACCOUNT_NUMBER,
6                 'STATUS',
7                 LOOKUP.MEANING) 


Looking at it like that tells me your DECODE is missing a default value.

In future when posting can you please follow the posting guidelines found in the orafaq forum guide: http://www.orafaq.com/forum/t/88153/0/

Other than that - if you're on Oracle 9i or higher I strongly recommend you use the CASE statement for this rather than DECODE, it's a lot easier to use.

EDIT: typo

"fn"? "o/p"? don't use IM speak.

im formatting my decode statement:

ORDER BY
DECODE(nvl(UPPER('&&order_by'),party.party_name),
'CUSTOMER NAME',PARTY.PARTY_NAME,
'CUSTOMER NUMBER',CUST_ACC.ACCOUNT_NUMBER,
'STATUS',LOOKUP.MEANING))

ITS WORKING CORRECTLY WHEN I SELECT CUSTNAME,NUMBER OR STATUS BUT IF I DONT SELECT ANY OPTION IT MUST PRINT ACCORDING TO CUSTNAME.
THE NVL FUNCTION IS NOT WORKING CORRECTLY please HELP ME IS THERE ANY WRONG IN MY DECODE STATEMENT.

I HAD SOLVED IT.
THE CORRECT STATEMENT IS:
ORDER BY
DECODE(UPPER('&&order_by'),'CUSTOMERNAME',PARTY.PARTY_NAME,
'CUSTOMER NUMBER',CUST_ACC.ACCOUNT_NUMBER,
'STATUS',LOOKUP.MEANING, PARTY.PARTY_NAME)
