Supplier Audit Bank report

Question

I am building a report which contains the supplier,bank and account details along with the changes made to Bank and Account details (Previous Value and New Value).
For this I have created a Materialized view (for holding previous data) and a view (To hold present data) and written a query to fetch supplier details , change details and also a flag which displays 'Y' if there are any changes happen to Bank site or Account details else it is 'N' by joining these two views.
The problem coming with the query if a supplier contains more than one bank accounts. its comparing the first account with the second account and treating it as a changed record and thus making the flag as 'Y' even though the record is not changed.
EX:
Data in Materialized View:
Supplier_No Branch Account_Number
1 B1 N1
2 B2 N2
3 B2 N3
4 B3 N4
Data in the View :
Supplier_No Branch Account_Number
1 B1 N11
2 B2 N2
3 B2 N3
4 B3 N4
here Account Number for supplier 1 is changed to N11 from N1, so I need to set the flag as 'Y' for this record and display the old and new account value. But it also updating the flag as 'Y' for the Supplier 2 as it is having two accounts and the first account in the MATERIALIZED VIEW compared to second account in the VIEW and treated it as a UPDATED account. Please help me out how to get this done. I have pasted the query which I was used to do this.

Hi Prasad,
Is this an custom report or standard report.
in case you want to count the vendor names having same name in then better check it at PO_VENDORS
select VENDOR_NAME from po_vendors
having count(VENDOR_NAME)>1
group by VENDOR_NAME
Thanks,
Ajit
