Difference between FS10N and FBL3N

Question

Friends,
When we run the FS10N report for a G/L a/c in a company code for the year 2007, it only shows an open balance of X amount. This amount is only for a particular business area. I have checked the settings and the report is not restricted for that business area. In fact when I run FS10N by excluding that business area I do not get any line items.
However, when we run the report FBL3N for the same a/c for the same company code for open items as on 08-Aug-07, we get another amount Y, which is far bigger than X and contains the line items for all business areas.
Can you please explain why this is so and what needs to be done so that the amounts of the FS10N and the FBL3N reports are same.
Also, no archiving or deletion of data has been carried out in the system.
Thanks & Regards.

Hi Sameer,
GL account balance- The balance of a G/L account is the sum of the debit and credit balances of the account.
There are two types of balances:
Credit balances
Debit balances
Structure: The account balance displays the following:
The opening balance (the balance carried forward from the previous year)
The total of all transactions for each posting period, broken down into debit and credit postings (transaction figures)
From these figures the system also calculates the following for the account balance display:
The balance per posting period
The accumulated account balance
From the SAP Easy Access menu, choose Accounting->Financial Accounting-> General ledger->Account->Display balances.
Enter the G/L account number, the company code, and the fiscal year. You can also limit the display for a specific business area.
You can save your selection criteria as a  selection variant. The next time you start the account display, the parameters you selected are already set. To save your settings, choose Goto-> Variants->Save as variant...

============================================================
FBL3N- You can display the line items for one or more accounts.
Line items are document items that were posted to a specific account. In contrast to a document item, a line item only contains the information from the document that is relevant from the account view.
You can display the following line items:
Open items
Cleared items
Noted items
Parked items
Items with special G/L transactions (in Accounts Receivable and Accounts Payable)
Items with customer or vendor items (in Accounts Receivable and Accounts Payable)
You can display the line items for the following account types:
Customer accounts
Vendor accounts
G/L accounts
Prerequisites
In order to display the line items for an account, the account must be managed with line item display. This means that you have set the indicator Line item display in the master data of the account.
This setting is mandatory for customer and vendor accounts.
For G/L accounts, you have to make this setting in the account master data.
For more information about the Line item display indicator, see  Defining "Line Item Display"
Features
If you have posted a business transaction and want to display the line items, you have the following options:
Display the document and then the line items. For more information, see  Displaying Documents.
Display the account and then the line items.
You can use the following functions to display line items:
Line Item Display with the SAP List Viewer (ALV)
This is the standard function. The line items are displayed in a list where you can use the functions of the  SAP List Viewer (ALV) for creating the layout, for example, sorting, creating totals, and so on.
Classic Line Item Display
You can only use the classic line item display as a modification solution.
