Standard BAPI for T-code f-44

Question

Hi
I need to clear vendor open invoices using BAPI's for T-code F-44 .I've got through various FM like <b>bapi_acc_document_post</b> and <b>bapi_ar_acc_getbalanceditems</b> but could'nt find solution because this FM's are for customer clearing the open items from table BSAD(cleared accounts of customer).Have any boby worked on this tcode to clear vendor accounts using bapi's or do we have any standard FM to use the scenario same as FM mentioned above for table BSAK(vendor clear items).
Its really simple working with bdc's to transfer data from flat file to the above transaction.But as known every vendor has huge sets of items and this could be a huge performance issue....so to avoid this in future we need to work on this using exclusively BAPI's......Any suggestions or sample codes wud surely be appreciated....
Thanks in Advance......

Thanks for ur response Anji Reddy garu,
I've tried to check up this given FM but could'nt find it here in my sap system both in QAS and in DEV more  the FM <b>Bapi_payit_post_clearing</b> is also not available here in my sap system what could be the problem it should display this standard FM if available right but its say FM does not exit......Can u do me a favour of forwarding the source code for both the FM's so that i can create a new customizing FM if its fits my requirement.....
