Project invoice XML references the wrong invoice

(4) Share

Report

Posted on by Gabriele Labunskaite

In D365 Finance & Operations, free text invoices generate the correct XML, but project invoices do not. When printing/sending a project invoice, the generated XML incorrectly references the first invoice ever created instead of the current invoice being posted.

Expected:
The XML should show the current project invoice number and details.

Actual:
The XML pulls invoice identifiers from the first historical invoice, causing incorrect invoice references in the output (i.e. if we are in project invoice SI817-012345, and print/send this, the XML generated will be for invoice SI817-000001).

Notes:
Issue only occurs for project invoices; free text invoices work correctly.

Question for the community:
Has anyone seen this issue where project invoice XML binds to the first historical invoice instead of the current one?
Is there guidance on what needs to be done to fix this?

Hi,

Can you tell more about your setup and technology used for generating these XML files? Are you using standard features (which one), an ISV, or customizations?

Hi Andre,

I am using standard functionality, I have imported the XML format from the Microsoft repository and I have set this format up under Sales Ledger parameters > Electronic documents (see below)

I have also set this up in print management, see below

I have done the exact same setup for free text invoices, and these invoices generate correctly. However, it is projects that seems to be having an issue and not generating the correct invoice for the XML.

As far as I am aware, we do not have any customisations.

Let me know if you need further information.

Thanks

Gabby

Hi,

Do you want to use e-Invoicing?
Ref. to the screenshot from Customer parmaeters > Electronic documents, it will assigned configuration for sending an invoice electronally (Send button) while on the next screenshot shared, it is realted to printing or veiwing a document.

If you use standard configuration like OIOUBL Project invoice, it should work.

Hi Alireza,

That is correct, this setup is to allow our Belgium entity to send invoices electronically as per the new January 2026 mandate.

In regards to project invoices, no matter the function used - print, view or send - they all fail to generate the correct invoice on the XML invoice. However, If we run the standard SSRS report, it picks up the correct invoice number we are trying to send. But, the XML generates the very first project invoice created- as if it is struggling to pull through the correct Record ID when generating the XML?

Thank you for sharing the link to DynoFOTech, I have used this website for my setup and followed the steps listed, as well as the steps on the Microsoft Learn pages: https://learn.microsoft.com/en-us/dynamics365/finance/localizations/belgium/emea-bel-e-invoices. However, there is no stipulation on further project setup, which could be causing the issue.

When you have setup project invoices for other countries for e-invoicing - was there any additional setup required? Did you run into the same issue as we have?

Thanks

Gabby
