How to Calculate With holding taxes using BAPI's

Hi,

I have to upload Vendor Invoices using FB60/Fb01 tcodes. I am able to post the Invoices using FB01/Fb60 but I have to calculate with holding taxes also using this program for the Invoices.

Does anyone has any idea how do you calculate with holding taxes using any BAPI's?

I have used these two BAPI's

BAPI_ACC_DOCUMENT_POST

BAPI_acc_invoice_receipt_post

they are working fine but no without withholding tax.

Your inputs are appreciated. I did searched on SDN and couldn't find any solution for this.

Regards,
