You must provide a reference to the original invoice the MyInvois UUID that was received back from the portal when the original invoice was uploaded and accepted.

This information must be provided in the Preceding Invoice Reference Group and is used in the following invoice types:

Description	VRBL Value	Standard Value
Credit Note	`VRBL:MY:02`	`381`
Debit Note	`VRBL:MY:03`	`381`
Refund Note	`VRBL:MY:04`	Not applicable
Self-Billing Credit Note	`VRBL:MY:12`	`261`
Self-Billing Debit Note	`VRBL:MY:13`	`527`
Self-Billing Refund Note	`VRBL:MY:04`	Not applicable

Elements

Use the following subelements of the BillingReference element:

Element (Path)	Cardinality	Description
Preceding Invoice Reference (`/Invoice/BillingReference`)	0..n	A group of elements providing information regarding preceding invoices.
Invoice Document Reference (`Invoice/InvoiceDocumentReference`)	1..1	A group of elements providing information regarding invoice references.
Preceding Invoice Reference (`Invoice/InvoiceDocumentReference/ID`)	1..1	The identification of an invoice that was previously sent by the Supplier.
Preceding Invoice Reference UUID (`Invoice/InvoiceDocumentReference/UUID`)	1..1	The MyInvois UUID. The unique identifier number that is issued by MyInvois portal after the original invoice is uploaded by the Supplier.

Restrictions

For exceptional cases, you can use NA where the UUID is not available, in the Preceding Invoice Reference UUID (Invoice/InvoiceDocumentReference/UUID) element.
This topic and the Malaysia B2B/B2G: Supplier's Billing Reference Number topic both use the BillingReference element. An example of how to model both simultaneously is included below.

Example

Single preceding document reference

This example shows a single reference to a preceding invoice:

<Invoice>
    <!-- Code omitted for clarity -->
    <cac:BillingReference>
        <cac:InvoiceDocumentReference >
            <cbc:ID>INV12345</cbc:ID>
            <cbc:UUID>SDCJ2PPVF9HX4XAFZ091W3EJ19</cbc:UUID>
        </cac:InvoiceDocumentReference>
    </cac:BillingReference>
    <!-- Code omitted for clarity -->
</Invoice>

Combined example with Supplier's billing reference number

This example shows two uses of the BillingReference element, one for the preceding invoice and one for the Supplier's billing reference number:

<Invoice>
    <!-- Code omitted for clarity -->
    <cac:BillingReference>
        <cac:InvoiceDocumentReference>
            <!-- Preceding Invoice Reference -->
            <cbc:ID>INV12345</cbc:ID>
            <cbc:UUID>SDCJ2PPVF9HX4XAFZ091W3EJ19</cbc:UUID>
        </cac:InvoiceDocumentReference>
    </cac:BillingReference>
    <cac:BillingReference>
        <cac:AdditionalDocumentReference>
            <!-- Supplier Internal Billing Reference Number -->
            <cbc:ID>E12345678912</cbc:ID>
        </cac:AdditionalDocumentReference>
    </cac:BillingReference>
 <!-- Code omitted for clarity -->
</Invoice>
