# Update 27.2.202607.156470

Release Date: 11. February 2026

## ![](https://cdn.document360.io/b53c92b4-6b2d-4730-b8fc-fa2e7b107470/Images/Documentation/Summary.svg) Release Summary

  

This release extends the OIOUBL electronic invoice export with two new capabilities. **Sales invoices and credit memos** can now include the customer's reference (the "Your Reference" field) in the electronic document, and descriptive comment lines from your sales documents can be carried through to the electronic invoice.

- The **"Your Reference"** field is now mapped to the `BuyerReference` element in the OIOUBL XML, helping customers route and match electronic invoices in their own systems
- **Comment lines** (blank-type lines with a description but no item or amount) can now be included in electronic invoices and credit memos sent via Sproom
- Both features are controlled by settings in the Sproom Connector setup

**Customer Reference in Electronic Invoices**

Electronic invoices sent via Sproom now include the **"Your Reference"** field from the sales document as the buyer reference (`BuyerReference`) in the OIOUBL XML. This allows the recipient's system to automatically match and route the incoming electronic invoice based on the reference the customer provided when placing the order.

**Add Comment Lines** ([documentation](/docs/features/add-comment-lines))

Electronic Invoicing with Sproom now supports including **comment lines** — blank-type document lines with a description but no quantity or amount — in the OIOUBL electronic invoice and credit memo. Enable the **Add Comment Lines** toggle in the Sproom Connector settings to ensure descriptive text lines, notes, and terms entered on the sales document are preserved in the electronic document sent to the recipient.
