Thailand Localization - TAX Reports

This module adds a Thai Tax Report to the Accounting reporting menu. Users open the wizard, pick a company, a tax and a period, then choose View, Export PDF or Export XLSX.

• The tax list is limited to taxes that are due on invoice, used for sales or purchases, and not included in the base amount.
• The report lists each tax invoice line with date, tax invoice number, customer/supplier, tax ID, branch ID, base amount, tax amount and document reference, plus totals for base and tax.
• Cancelled or reversed documents are shown with a (VOID) marker and zero amounts, so they appear in the report without affecting the totals.
• The report title changes to Sale VAT Report or Purchase VAT Report depending on the selected tax.
• Results are computed on the fly and are not stored in the database.

The report is available as an on-screen view with Print and Export buttons, as a PDF using an A4 portrait paper format, and as an Excel file with one sheet per report. It reads tax invoice data from account_move_tax_invoice and account_move_line, and is available to accounting users and managers.
