Determination 2026.02 patch release notes

UAT EMEA Release Date: March 11, 2026
UAT AMER Release Date: March 12, 2026
PROD EMEA Release Date: March 24, 2026
PROD AMER Release Date: March 31, 2026

What's fixed

Implementation - Net Tax Amount per Unit (5021027)
This release introduces a new field in the REST API tax calculation response to address a gap in per-unit tax reporting for line items with quantities greater than one. Previously, when calculating taxes for multi-quantity items with related adjustments (coupons, rebates), the system returned netTaxAmount as an aggregate amount across all units and taxAmountPerUnit without net adjustments applied. This required downstream systems to perform division calculations to derive net per-unit amounts, which could introduce rounding inconsistencies. The new
netTaxAmountPerUnit
 field ensures all tax calculations and rounding remain within ONESOURCE Indirect Tax Determination, eliminating the need for downstream recalculation.
Key changes:
  • Added new
    netTaxAmountPerUnit
     field in REST API response at /sabrix/v1/calculate endpoint.
  • Field appears within each authority tax block and tax summary at the line item level.
  • Calculation logic: netTaxAmount ÷ Quantity = netTaxAmountPerUnit.
  • Field structure includes 4 required sub-fields:
    documentAmount
     (rounded),
    unroundedDocumentAmount
    ,
    authorityAmount
     (rounded), and
    unroundedAuthorityAmount
    .
  • Display behavior
    : Field only appears when line item quantity is greater than 1; omitted for single-quantity items.
Certificate Manager – Certificate Sync Timeout (5175936)
An issue was identified in the AMER UAT AWS environment where certificate imports were timing out and leaving certificates in a non-synced state. This was caused by database contention specific to that environment and was blocking tenant validation workflows. A targeted fix has been applied to reduce database contention and restore certificate sync functionality.
Certificate imports now complete successfully and certificates are reflected in the correct synced state.
TransEditor – Checkout Slowness (5165783)
An issue was identified in the AMER UAT AWS environment where TransEditor checkout was taking several minutes to complete, significantly impacting core configuration workflows during UAT validation. This was caused by underlying database contention specific to that environment. A fix has been applied to address the database contention and restore expected checkout performance.
Custom Rules – Add Custom Product Returns 412 Error (5169828)
An issue was identified where attempting to add a custom product from the Custom Rules page failed with a "start date must not be null" validation error. This occurred because a backend validation change introduced a requirement for a Start Date value that was not surfaced in the UI, causing all add attempts to fail. The fix introduces a mandatory
Start Date
 field and an optional
End Date
 field in the Add Custom Product UI, aligning the interface with backend validation requirements. Users can now successfully add custom products from the Custom Rules page without encountering this error.
LineNumbers - Alphanumeric Values Rejected in Tax Calc API (5180414)
An issue was identified with the Tax Calculation API endpoint where tax calculation requests failed if the
lineNumber
 field contained alphanumeric values. This behavior differed from the previous versions, which accepted string‑based line numbers, and caused unexpected validation errors for existing integrations. The fix restores support for alphanumeric
lineNumber
 values, ensuring backward compatibility and allowing requests to be processed successfully.
