  2. Go to the Invoices and Credit Memos view
  3. Select the relevant Intercompany Invoice which was created automatically by system based on customer invoice
  4. You can see that Tax Code is wrong


Always intercompany supplier invoice details will be based on respective customer invoice.

As you know Tax Code = Tax Event + Tax type + TAX Rate Type + tax Deductibility.

Tax event used in customer invoice tax code determination will be used for determining the tax event to be used for determination of tax code of supplier invoice.


Check the tax code used in customer invoice and then check the business configuration for respective tax event of that tax code.

Please refer the excel attached that shows standard mappings of tax events of sales side with purchase side tax events.

so check if mapping of tax event is there in the attachment,

If its there then the respective purhcasing tax event is used to determine the tax code in supplier invoice and thus Automatic tax determination flag is not checked in supplier invoice. also the tax country  in supplier invoice will be same as that of  respective customer invoice .

If its not there then system takes all details of the supplier invoice to determine the tax event ,tax country and  then tax code accordingly where you will see that Automatic tax determination flag is checked in supplier invoice.
