  • Product: ONESOURCE E-Invoicing

R2.0.0 April 27, 2026 release notes

Party Name column and filter added to documents and error grids

  • Added a new
    Party Name
     column to the Documents grid, displaying the customer name for AR (Accounts Receivable) invoices and the supplier name for AP (Accounts Payable) invoices, giving users greater clarity and visibility into invoice data at a glance.
  • Introduced a new
    Party Name
     filter on the Documents grid, allowing users to search and narrow down invoices by customer or supplier name without needing to know the invoice direction upfront.
  • The
    Party Name
     filter searches across both AR and AP transactions by default when no invoice direction is specified by the user, ensuring comprehensive search results regardless of transaction type.
  • Extended the
    Party Name
     column and filter to the Errors transaction grid, ensuring a consistent user experience and search capability across all relevant grid views.

Tax Identification number added to Documents page

  • Added
    Tax Identification Number (TIN)
     to the document data details view, enabling users to distinguish invoices that belong to the same legal entity operating across different countries.
  • The
    Tax Identification Number
     field gracefully handles missing data — when a TIN is not available for a given invoice, the field is left blank while the invoice remains fully visible and accessible with all other available information intact.
  • Introduced a new
    Tax Identification Number
     filter on the Documents page, allowing users to search and narrow down invoices by TIN for faster and more precise identification of legal entity-specific records.

Pagero archive index file retrieval via OEI API

  • Introduced a new
    Attachments
     accordion on the
    Preview
     tab of the
    Documents
     page, enabling users to view and download the
    ArchiveIndex.xml
     file directly from the document preview section.
  • The
    ArchiveIndex.xml
     file is surfaced within the
    Attachments
     accordion with dedicated
    View
     and
    Download
     actions, allowing users to access the archive index without leaving the document preview experience.
  • The
    Attachments
     accordion is conditionally displayed — it only appears when the
    ArchiveIndex.xml
     file is present in the document's attachments, keeping the UI clean and uncluttered for documents that don't contain an archive index.
  • The new
    Attachments
     accordion is positioned last in the
    Preview
     tab, appearing after the existing
    Invoice
    ,
    Clearance
    , and
    Business
     accordions, and follows the established accordion design patterns for a consistent user experience.
  • This enhancement supports
    legal compliance
     requirements by providing users direct access to the
    ArchiveIndex.xml
    , which contains cryptographic hashes and references for the source, target, and presentation files associated with a transaction.

ONESOURCE LogCenter: Enterprise-Grade troubleshooting

The legacy Unified Logging system is being replaced by the
LogCenter
, a centralized hub designed for high-volume invoice lifecycles.
  • The ONESOURCE
    LogCenter
     centralizes the management of application logs.
    LogCenter
     also enhances the way you monitor and troubleshoot ONESOURCE products by providing a single, unified platform for log collection, search, and export.
  • LogCenter
     will fully supersede the existing
    Unified Logging
     feature, providing a standardized logging infrastructure.
  • The system seamlessly integrates with all ONESOURCE products—both cloud and on-premises—allowing for comprehensive log visibility, simplified compliance, and streamlined troubleshooting.
  • Significantly faster log search and retrieval times due to Parquet optimization and detailed partitioning.
  • LogCenter
     offers a secure, structured, and easily searchable record of all key user activities and system events.
  • A step-by-step guide about ONESOURCE
    LogCenter
     is included in OEI2026.R2.0.0 User Guide.
  • The legacy
    Unified Logging
     system is being replaced by the
    LogCenter
    , a centralized hub designed for high-volume invoice lifecycles.
    • Extended Data Retention:
       Visibility has been expanded from the previous 30-day limit to 6 months of historical logs, supporting long-term audit requirements for high-payload environments.
    • End-to-End Traceability:
       Using a unique
      Correlation ID (Transaction ID)
      , users can now track a single document's journey across all integration points (Core, Oracle, Coupa, SAP Ariba, etc.) in one unified view.
    • Performance & Export:
       Experience significantly faster response times for log queries and the ability to Export to CSV for offline analysis and reporting.
    • Granular System Control:
       Administrators can now switch on and off the log capturing at the specific service level (e.g., Oracle, SAP, Coupa or SAP Ariba) to optimize data focus.
    note
    Unified Logging
     remains available in the UI until the R3 release for viewing historical data. However, all new log activity starting in R2 must be managed via the
    LogCenter
    .

New ERP connectivity: Coupa integration (AP invoice and business response)

Overview
OEI continues to expand its ecosystem with a native connector for
Coupa AP Invoices
.
  • Automated Compliance:
     Seamlessly bridge the gap between procurement and tax. Invoices generated in Coupa flow directly into ONESOURCE E-Invoicing for tax validation and global mandate clearance.
  • Synchronized Statuses:
     Legal statuses and PDF clearances are pushed back into Coupa, ensuring the procurement "Source of Truth" is always up to date.
This release introduces AP Invoice posting from ONESOURCE Pagero E-Invoicing to Coupa and Business Response from Coupa into ONESOURCE Pagero E-Invoicing application. This enhancement improves visibility, compliance, and operational efficiency to view the AP Invoice posting and present status of the AP Invoice.
Key update
AP Invoice posting to Coupa and Invoice Status Fetch from Coupa via Coupa REST API
ONESOURCE now connects to Coupa using the Coupa REST API for AP Invoice Posting and to fetch invoice statuses and update the Business Status column within the ONESOURCE application.
Mapping of supported Coupa Invoice document status in ONESOURCE Pagero:
Coupa invoice status
ONESOURCE Business status
On Hold

Benefits of the Integration:
 The AP Invoice Posting integration streamlines invoice submission to Coupa, improves accuracy through automation, and provides real-time status tracking in ONESOURCE, enabling proactive issue correction without buyer intervention.
