    • isTaxIncludedSummarySupported

      default boolean isTaxIncludedSummarySupported()
      Does this provider correctly handle a tax-included price combined with a summary tax?
      The native calculation (StandardTaxProvider) does not, so this combination is forbidden for it (see IDEMPIERE-6749).
      A custom provider that delegates the whole tax calculation and computes this case correctly can override this method to return true, allowing the line to be saved (see IDEMPIERE-7069).
      Returns:
      true if the provider computes a tax-included summary tax correctly - false by default
