Additional line item need to add while posting Invoice FB60/MIRO

Hi Team,

Need your expert opinion related below issue.

Our client has the unique requirement for Consumption Tax calculation, They want to pay the Consumption Tax to vendor but they did not want to show as part of  Vendor invoice Amount. Instead of that hey want to show a additional line item as Debit and Credit on Invoice, which will display in Document but it wont be a part of Vendor invoice Amount. Please see the below scenario.

Service Value                                     Dr        10000            

CT Charges Account – 5%                Dr        50                   

Vendor Account                                Cr        9475              

WHT Tax 5.25% Account                  Cr        525                

WHT Tax 0.50% Account                  Cr        50  

Can you please advise process or BADI or Program to fulfill this, as business does not want to do the manual entry for the Consumption Tax entry.

Thanks and Regards

Vinay
