Basware has identified an issue affecting the visibility of certain invoice import failures in AP Automation.
Issue Start Date
The issue was introduced when AP Automation release 26.5 was deployed to customer environments.
Impact Summary
A change introduced in AP Automation release 26.5 to improve invoice import performance altered the way invoice save errors are handled.
Under certain circumstances, if an invoice import fails due to an underlying processing error, the failure may not be reported correctly. Instead, the invoice may appear as successfully delivered in BT and the Portal with the standard acknowledgement message "oK".
The issue does not itself cause invoice import failures. Rather, it prevents certain invoice import failures from being reported correctly, making it appear that an invoice was delivered successfully when it was not successfully imported into AP Automation.
As a result:
Impacted Documents
Basware has identified the invoices affected by this issue and is proactively notifying impacted customers.
If you have concerns regarding invoices submitted during the affected period, please contact Basware Support. Basware can provide information about the affected invoices identified in your environment, investigate the underlying cause of the invoice import failure, and advise on any required corrective actions.
Affected invoices may appear as successfully delivered in BT and the Portal with the acknowledgement message "oK", even though they were not successfully imported into AP Automation.
Where necessary, Basware Support will assist with determining the appropriate remediation, including reprocessing or resubmitting affected invoices.
Solution
Basware has identified the root cause and implemented a corrective fix.
The fix restores the expected error handling behaviour so that invoice import failures can be detected and reported correctly.
The fix will be deployed as part of AP Automation release 26.7 and maintenance release 26.6.4 between 23 July 2026 and 27 July 2026.
Customers will receive the fix as part of their scheduled AP Automation release deployment. The deployment date depends on the release phase applicable to their environment. Customers can find their exact deployment date under Service Status > Extended Release Schedule in the Basware Customer Service Portal.
After the Fix
The corrective fix prevents future occurrences of this issue by restoring the expected error handling behaviour for AP invoice imports.
After the fix has been deployed, Basware will reprocess the invoices identified as affected by this issue.
Reprocessed invoices will receive the correct delivery status and acknowledgement message based on the outcome of the AP import. If an invoice import fails during reprocessing, the actual error message will be returned, allowing the underlying cause of the import failure to be identified and addressed.
In some cases, reprocessing may result in an invoice being imported more than once if the invoice has already been successfully imported into AP Automation through other corrective actions. AP Automation duplicate detection controls will identify such invoices and mark them as duplicates for review.
Customers do not need to take any action at this stage. Basware will perform the reprocessing after the fix has been deployed.
Further Support
If you believe you are affected by this issue, or if invoices are missing from AP Automation while appearing as delivered in BT or the Portal with the acknowledgement message "oK", please raise a case with Basware Support.
