Resolved issues

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

February 26, 2026

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 .

Issue	Solution
In India, suppliers were prevented from saving or sending invoices after attaching a pre-cleared invoice (JSON file).	Corrected the issue so Indian suppliers can save and send invoices with a pre-cleared JSON file invoice attached.

Issue	Solution
On the Supplier Connect portal, some suppliers who answered "N/A" or "No" to certain questions still received an error message and were unable to proceed with their implementation past the "Questionnaire" step without uploading the contingent required invoice file.	Deployed updated metadata file so suppliers can now save the questionnaire without uploading a dummy file for any questions marked "N/A" or "No."

Issue	Solution
Onboarding users were unable to select zero-rated tax categories on the "Questionnaire" screen in the Supplier Connect portal.	Adjusted settings so that suppliers can now select zero-rated tax categories during their self-service implementation.
Following recent changes to the portal login screen, the page no longer accepted submission of a user's email address by pressing the Enter key. Users needed to select the "Sign In" button to proceed.	Corrected the issue so that users can submit their email address on the portal login screen by either selecting "Sign In" or pressing Enter.
When customers created a new account with a VAT number/Tax ID that consisted only of numbers (no letters), the VAT number/tax ID did not persist across the registration process.	Fixed the issue so that the VAT number/tax ID is preserved on all registration screens.

Issue	Solution
In Italy, when two suppliers used the same invoice number and the buyer retrieved both invoices from the government SdI platform, when the buyer used the "Find" option on the "Invoice status" page and clicked on the second instance of the invoice number, the system displayed the first invoice with that number.	Ensured that where an invoice number appears multiple times and the user selects an invoice to view, it is the selected invoice that is displayed.

Issue	Solution
The French translation for the Unit of Measure "Carton of 1" was missing from the database. This prevented suppliers from converting a Purchase Order with that Unit of Measure, as they received the following error message: "Impossible de convertir un bon de commande sans article" ("Unable to convert a purchase order without an item").	Added the French translation for the Unit of Measure "Carton of 1" to the database.
In a previous deployment, we added a separate section for customers in Mexico to provide additional information required for invoice processing in Mexico. These fields were also incorrectly added to be visible on the "Company details" section for customers in Saudi Arabia.	Removed the section pertaining only to customers in Mexico from the "Company details" section for customers in Saudi Arabia.

Issue	Solution
Italian accounts were missing the "*" mandatory field indicator on the City and Post Code fields.	Added "*" mandatory field indicators to the City and Post Code fields on Italian accounts.

Issue	Solution
Users were unable to change their preferred multifactor authentication method: from SMS to email from Twilio app to email from SMS to authentication app	Resolved issue so new preference selected by a user on the "Update your MFA" screen now saves correctly.

April 29, 2025

Issue	Solution
Some suppliers received an error message when trying to acknowledge their buyer's purchase orders on the portal.	Adjusted settings to allow suppliers to successfully acknowledge purchase orders and proceed with converting the PO to an invoice.
