Can we enrich self-billing invoice by tax code after is produced?

[former_member711396]

I'm currently working with a client in the Netherlands implementing our SAP Procurement Solution (SAP Fieldglass, Ariba P2P and SAP ECC v.6) The client is generating a self-billing invoice in SAP Fieldglass, Fieldglass is creating a PDF. Once this invoice leaves Fieldglass and is sent to Ariba B&I, Ariba enriches the invoice by tax code N6 based on the tax information sent from Fieldglass. My client is asking whether this is still compliant scenario in terms of valid self-billing invoice? My guess here is that tax code is purely statistical information within the ERP and not legally required information to be present on the invoice thus my answer would be yes, tax code enrichment should not impact the self-billing PDF.
