This issue applies to sites configured to use the enhanced invoicing user interface (the parameter Application.Invoicing.UseEnhancedInvoice is set to Yes).

When a tax line on an invoice is assigned a tax code, that tax code isn't carried through to the IR. There was no way to enforce the IR to retain the tax code assigned on the invoice.

Now, the new site configuration parameter Application.Invoicing.CopyTaxCodesFromInvoiceToIR determines whether the tax codes on IR tax lines originate from the corresponding invoice tax line.

• If set to Yes, the tax code on an invoice tax line is copied to the corresponding IR tax line. If there's no valid tax code that matches the invoice line, tax calculation fails on the IR. If invoice tax lines don't have any tax code specified, the corresponding lines on the IR won't have a tax code in IR either. This is the case regardless of whether the site is using the enhanced tax computation engine (set via the parameter Application.Invoicing.UseTLCTaxEngine).
• If set to No (the default), the tax code on the IR might be different from that on the invoice. The tax code is calculated using a lookup. The lookup used depends on which tax computation engine your site is using, as determined by the parameter Application.Invoicing.UseTLCTaxEngine.

Note: If the tax code on the IR is different from what’s expected, it might be because the site’s tax configuration needs correcting. Address any tax configuration issues before you consider setting this parameter to Yes.

Action required

To configure your site to copy tax codes from invoices to IRs, have your designated support contact log a Case. SAP Ariba Customer Support will follow up to complete the request, setting the parameter Application.Invoicing.CopyTaxCodesFromInvoiceToIR to Yes if appropriate for your invoicing solution.
