Automatic Clearing for Customers and Vendors

Question

Hi,
We want to clear the open items at a time for the customers and vendors.
Ex: Cutomer "A" contains 15000 Dr(20 Line items), 12000 Cr(15 Line items) and closing balance 3000 Dr
Now we want to clear the all open items at a time and remaining(3000 Dr) balance for open items.
We don't want Manual Clearing(F-32)
Is this possible through F.13 or others? 
Thanks in advance

No you cant
The automatic program groups items from an account together where they have the same
entries in the following fields:
• Reconciliation account number
• Currency
• Special G/L indicator
• Five freely defined criteria from document header or line item, for example,
assignment field, reference number, and so on.
If the balance, in local currency, of the items within a group is zero, the system
automatically clears them and creates clearing documents.
All accounts requiring automatic clearing must be defined in Customizing.
The automatic clearing program does not clear:
• Noted items
• Statistical postings and certain special G/L transactions relating to bills of
exchange
• Down payments can only be cleared if down payment clearing items of the
same amount have already been posted.
• items with withholding tax entries
