Enhanced tax calculation, units and visible fields

Enhanced Edition can use configured ordinary tax calculation and multiple units, but has no tax-authority interface or tax daily/monthly reports.

Steps

1. Review the business need before enabling tax or multiple units in company settings.
2. For ordinary tax, verify source rules, product classification and tax-inclusive pricing; do not enable an unverified regional scheme.
3. Maintain conversions and unit prices before testing multi-unit document quantities and totals.
4. When disabled, related report columns and column options remain hidden, with exports using the same scope.
5. When sharing a database with POS, respect the edition boundary without clearing tax-authority settings used by the other edition.
