The CFDI 4.0 format enables the taxpayers to include document supplements in order to extend the data reported to the SAT for specific business scenarios. In VRBL, there is a mechanism to enable these supplements. In order to make use of the supplements, it is required to add an invoice extension with the list of complements the taxpayer wants to include in the CFDI.

This extension is in Invoice/UBLExtensions/UBLExtension/ExtensionContent/InvoiceExtension/DocumentSupplements, and an instance of Supplement should be included per supplement.

VRBL currently supports the following supplements within the Invoice document type.

Example

<ubl:Invoice>
	<cec:UBLExtensions>
		<cec:UBLExtension>
			<cec:ExtensionContent>
				<vrbl:InvoiceExtension>
					<!-- Code omitted for clarity -->
					<vrbl:DocumentSupplements>
						<vrbl:Supplement>VRBL:MX:ForeignTrade</vrbl:Supplement>
					</vrbl:DocumentSupplements>
					<!-- Code omitted for clarity -->
				</vrbl:InvoiceExtension>
			</cec:ExtensionContent>
		</cec:UBLExtension>
	</cec:UBLExtensions>
	<!-- Code omitted for clarity -->
</ubl:Invoice>
