Tax Distribution Accounting date unable to update for ISP PO Matched Invoices

Tax Distribution Accounting date unable to update for ISP PO Matched Invoices.

We have an Entity in Poland where ISP Invoices raised with Date 3rd Mar 2026 and eventually it landed in AP Module with the same date and Accounting Distributions carried the same date 3rd Mar 2026 . With the new Privilege Edit PO Matched Invoices user has updated the Invoice Data and Line Accounting date as 28th Feb 2026 . However the tax lines distribution is still carrying 3rd Mar 2026 and user unable to edit the accounting date .

This is Impacting the JPK_VAT (Generate JPK VAT Report) and Invoice count is showing in Feb 2026 and VAT details are appearing in Mar 2026 .
