TAX_RATE when subscription from Backend

Hi,
Dear

I see that when you create a backend subscription, and you manually modify net import / import / tax amount, the system set the tax_rate = 0.00%.

Is it possible to have a field also for tax_rate

-- or
allow the system to recalculate tax_rate from gross_amount and _tax_amount; calculation should be:

tax_rate = (tax_amount / (gross_amount - tax_amount) ) * 100

--

?

Very thanks.

Hello

Better please leave the amount inputs empty to allow the system to calculate and store tax rate, then you can edit the record and change the amount later after the record is saved if needed

Regards,

Tuan
