Resolved issues

This topic lists previously reported issues that are resolved in this Tungsten e-Invoice Network update.

September 26, 2026

Issue Solution

Some French domestic invoices failed clearance routing because supplier and buyer identity data (SIREN, VAT numbers, and electronic addresses) was taken from the routing infrastructure instead of the parties named on the invoice.

Resolved a set of circumstances in French clearance routing so supplier and buyer identity data now comes from the parties named on the invoice.

French addressing suffixes (suffixeAdressage) that contained a dot were rejected during onboarding on AP Inbound and AR Outbound endpoints.

Adjusted validation so addressing suffixes can contain a dot in any position.

The PA management screen showed non-French entities.

Fixed the PA Management screen so only French entities are visable.
Web Form Suppliers in Poland received an error on the 'Create invoice' page when they added additional partial payment information to a new invoice. Removed the additional partial payment input from the 'Create invoice' page, so suppliers no longer receive this error.

Issue Solution

Some French invoices were rejected incorrectly, left unresolved, or delivered outside the French clearance flow. Suppliers also had to enter payment terms and preceding invoice codes manually, even when only one value was possible.

Fixed several French clearance and validation issues. Routing-error notifications from the compliance platform are now treated as a final rejection instead of being left unresolved. Invoices that can't enter the French clearance flow are now rejected with a clear reason instead of being delivered as standard invoices. Self-billed invoices are no longer rejected when the supplier has no network account. Invoices are now accepted when a party provides either a SIRET or a VAT number, and a SIREN on its own is accepted as the VAT reference. Payment terms and preceding invoice codes are now auto-populated when only one value is expected.

In Poland, invoices that didn't finish processing and later changed to Failed status after reprocessing didn't appear on the Invoice Status Service (ISS) page.

Fixed the ISS page so these invoices now appear with their current status.

Issue Solution

Some users attempting to reset their password by selecting "Forgot password" were receiving two reset emails with different security codes at the same time, causing confusion and potential login failures.

Applied a fix to prevent multiple reset password emails from being dispatched simultaneously when a user triggers the "Forgot password" flow. Users will now reliably receive a single password reset email as expected.

Some Polish customers were experiencing processing issues, including improper field rounding, no automatic retry, and slow performance for large invoices.

Improved processing for Polish customers, including:
  • Updated invoice processing to preserve supplier-provided values by removing previous rounding behavior on selected KSeF fields.
  • Added automatic retries for clearance invoices that remain in an "In Process" state for more than 24 hours.
  • Improved notification retry handling, reduced unnecessary logging, and optimized performance for large invoices.

Issue Solution

Some customers were experiencing issues where data on invoices created using PO Convert was misaligned or missing entirely when the Ship To address contained more than five lines.

Updated the portal to support all seven Ship To address lines during PO-to-Invoice conversion. Address line values are now correctly mapped to the corresponding invoice fields up to seven lines, whereby the customer will now see correct, complete address information on the resulting invoices.

Issue Solution

The address information displayed on Tungsten's PDF for invoices retrieved from Polish government KSeF platform was truncated.

Tungsten PDFs generated for retrieved invoices will now display the complete address as available in the FA XML.

Some Polish customers were experiencing invoice submission or retrieval failures due to "timeout" issues where inbound/outbound volume limits enforced by the Polish government KSeF platform were being breached.

KseF introduced a batching mechanism to handle the volume of both inbound and outbound invoices, so Tungsten e-Invoice Network enhanced its processes to accommodate the same so that we do not get any throttling issues during clearance or retrieval actions. This enables more invoices to be received or sent within a period and reduces the risk of invoices failing due to "timeout" issues.

Some Polish customers were providing a single customer order number but seeing an extra order date with blank order number listed in the Orders ("Zamowienia") section of the Tungsten-generated PDF invoice, due to an error generated in the FA XML. Enhanced the Tungsten PDF template to display Orders ("Zamowienia") per order number information available in the invoice.

Issue Solution
Some customers were experiencing issues exporting reports containing larger datasets. Improvements were made to optimize both supplier and buyer invoice reports on the e-Invoice Network portal to improve performance for customers running reports over larger datasets.

For invoices submitted with an attachment file name containing multiple spaces, the 'Invoice status' page showed inconsistencies between the displayed file name and the received file name.

The issue was corrected and the displayed file name and the received file name now match.
Some Polish customers were experiencing issues with corrective invoices, including being unable to save line items, being unable to retrieve draft invoices, and generating inaccurate amounts on invoices with negative lines only. Deployed the following enhancements to support the processing of corrective invoices in Poland:

  • Identified and fixed an intermittent issue that caused users to be unable to save line items on the e-Invoice Network portal when creating some corrective invoices.
  • Fixed an issue that prevented Web Form users from saving and then retrieving corrective invoices from a draft state.
  • Made a minor adjustment to the business rule that generates Tax Rate Summary in Poland so that it works correctly with corrective invoices having negative lines only.

Issue Solution
The "View Error" button on the portal's "Invoice status" page appeared in English and was not being translated into all supported languages. Translations for "View Error" were added to the portal for the following languages: Bulgarian, Czech, Dutch, Hungarian, Italian, Polish, and Portuguese.
Some Malaysian suppliers were receiving a service unavailable error when attempting to access the "Create invoice" screen after selecting the option "Yes I am subject to the mandate and have cleared invoices through LHDN." Issue was fixed, allowing affected users to access the invoice creation page and submit invoices.
Some Polish Suppliers were having invoices rejected by KSeF with a “RachunekBankowy (Bank account) has invalid child element 'NazwaBanku' (BankName)” error message. Updated the portal for Polish Suppliers so that IBAN is a required field in "Remit to details" on their account page. Bank account number and IBAN are conditionally mandated fields in the KSeF schema, so that where bank details are entered, both references are required. Where this was missing, KSeF was rejecting invoices with the error message. "Bank account number" was already a required field.
Some Polish Web Form Suppliers were prevented from creating invoices using the Discount section. If "Apply a discount for early payment" was selected, the invoice failed validation. An update to the processing of discount information was implemented so Polish Web Form Suppliers can now successfully create invoices using the Discount section.
Some Polish Web Form Suppliers were prevented from creating invoices using the Carrier section. An update to the processing of carrier information was implemented so Polish Web Form Suppliers can now successfully create invoices using the Carrier section.
Some Polish Web Form Suppliers were prevented from updating an invoice from zero-rate tax categories to numeric tax categories. How tax rates are modified was changed to ensure Polish Web Form Suppliers can now successfully create invoices and corrective invoices using zero-rated tax categories.
Some Polish Web Form Suppliers were experiencing failed invoices when selecting "Paid" in the "Payment Information" field. A data processing inconsistency that prevented the successful processing of these invoices was corrected and Polish Web Form Suppliers can now select "Paid" under "Payment Information" when creating an invoice.
Some Polish Web Form Suppliers were experiencing KSeF validation failure when entering a value in the "Contractual Rate" field using a comma (,) as a decimal separator. KSeF requires the decimal separator to be a dot (.) The e-Invoice Network Web Form allowed submission of data using a comma (,), which it converted to a dot (.) on screen, but the generated XML contained the original comma entry, causing validation errors in KSeF. The Web Form was updated to ensure the XML was submitted with a dot in the input value submitted by the supplier under "Contractual rate" UI field.
On Polish corrective invoices, line item total calculations were not refreshing to display the inclusion of the tax amount before being saved. This issue related to the display of data and has been corrected. Polish corrective invoices now display the line item total including the tax amount immediately.
Some Polish suppliers were unable to view the clearance mandate options on the "Company details" page. An intermittent issue with translations was fixed and all clearance mandate options are now visible.

Issue Solution
Some Web Form Suppliers selected the incorrect currency by mistake when creating invoices on the portal due to the extensive number of currency options on the drop-down list, reflecting all possible currencies supported by Peppol. Removed infrequently used currencies from the selection list on the Tungsten e-Invoice Network portal, lessening the risk of suppliers accidentally selecting the incorrect currency. For example, the "United States dollar (next day)" option, which some customers had selected rather than "United States Dollar (USD)", was hidden.

Two scenarios that should have been exempt were affected by a Belgian Continuous Transaction Controls (CTC) restriction implemented on domestic transactions processing in Belgium that prohibits the sending of invoices unless both parties are enabled to send transactions through the Peppol network.

Beginning January 1, 2026, Belgian suppliers attempting to invoice buyers VAT-registered in Belgium but established outside of Belgium were having the transactions rejected. Likewise, suppliers VAT-registered in Belgium but established outside of Belgium attempting to invoice Belgian buyers were having the transactions rejected.

An exclusion option has been added to this restriction to enable customers that are VAT-registered in Belgium but not established in Belgium to continue invoicing across Tungsten e-Invoice Network .
