How it is possible to update the values of Tax Point Basis for past invoices on zx_lines

Hi all,
(Oracle Fusion Cloud Applications24B (11.13.24.04.0)In order to have the “VAT Liquidation Report for Italy” comparable for the“Purchase VAT Register for Italy” and “Receivables Sales VAT Register for Italy” we have find that the set up on the VAT CODE must have the “Tax Point Basis”= “Accounting”.

We see that this change to the set up is not retroactive. The “Tax_point_Basis” is taken from the “zx_lines”,

see the query in the attached “VAT declaration for Italy V.1.docx”. How works the “ Select Transactions for Tax Reporting”, it is correct that it update the zx_lines files? How we can update the values of the “Tax Point Basis”= “Accounting” for past invoices? We appreciate your contribution
