Issue while performing invoicing MIRO

Hi All,

While performing Miro, when we calculate the tax based on tax code for eg: U1(18% of input) the amount we enter to make the balance zero is it fetched frm BSEG table.

I want to pass the amount after calculating the tax frm bseg table. Right now iam passing WRBTR as the amount but this doesnt include the tax amt. Can anyone let me know the proper field that i need to pass to the BAPI which shud include the Amount+Tax amount.

Thanks
