Hi,
I am using BAPI_INCOMNGINVOICE_CREATE function module for cearting Invoice for a PO with referrence to Goods Receipt. In this case got a problem that if i did GRC for 10 Quantity for a Line Item in PO which consists 20 Quantity then i need to caliculate Tax Amount and add it to the Gross Amount of Bapi Header Structure Field Gross_Amount.
So can any suggest me how to pass caliculate Tax for only GRC and pass to Bapi Header Gross_Amount Filed.
